If you want to see a political wave forming a year before an election, watch the retirements.

They’re often a leading indicator for which direction a party is headed, and so far, 2018 is shaping up ominously for Republicans, who will be defending 40 open House seats this fall compared with the Democrats’ 20. By far the biggest and most consequential retirement announcement came in early April, as Speaker Paul Ryan told his colleagues he would not seek reelection to his House seat.

Far more Republicans are leaving Congress voluntarily than Democrats, putting the party’s control of the chamber in jeopardy. Several veteran Republican lawmakers in competitive districts are calling it quits, depriving the GOP of the advantage of incumbency in races that could determine control of the House in 2019.

At the same time, a wave of allegations of sexual harassment and other inappropriate behavior has scrambled the retirement picture in both parties, forcing several lawmakers to leave Congress early. Republican Representatives Patrick Meehan of Pennsylvania and Joe Barton of Texas, and Democratic Representative Ruben Kihuen of Nevada abandoned reelection campaigns after misconduct allegations. Scandals already forced the immediate resignations of Democratic Senator Al Franken and long-serving Representative John Conyers, as well as GOP Representatives Trent Franks and Tim Murphy. Representative Blake Farenthold of Texas first announced he would forgo his reelection bid after acknowledging he agreed to a taxpayer-funded harassment settlement with a former staffer. But in early April, he resigned from Congress altogether.

As for those getting out in 2018, Trump’s low approval rating and Congress’s meager legislative output may be contributing to the decisions of some Republicans to retire, including moderate Representatives Ileana Ros-Lehtinen of Florida, Charlie Dent of Pennsylvania, Rodney Frelinghuysen and Frank LoBiondo of New Jersey, and Dave Reichert of Washington state. But there are other factors at play. Unlike Democrats, Republicans have rules limiting the terms of their committee chairmen to ensure turnover and give younger members a chance to advance in the House. Congress isn’t as fun with less power, and six of the departing GOP committee leaders would be forced out of their roles and to the back bench in 2019.

Some Republicans untainted by scandal aren’t even finishing out their terms. Representative Pat Tiberi of Ohio left office in January to take a job with the Ohio Business Roundtable, and Dent announced in April that he would resign within a few weeks, having apparently determined that with the campaign season approaching, Congress wasn’t likely to get much more done this year. Meehan resigned on April 27 after earlier announcing plans to retire at the end of his term. Meehan wanted to short-circuit an investigation by the House Ethics Committee into allegations of inappropriate behavior towards a staff member, and he said he was repaying the government $39,000 for money used to settle the harassment case.

The trend to this point gives a distinct edge to the Democrats. While roughly the same number of lawmakers in both parties are leaving their seats to run for higher office, just 11 House Democrats are retiring outright or have already resigned, compared with 28 Republicans. (House members running for other offices often count as retirements, because it’s usually impractical or illegal to run for multiple positions at the same time.)

And although Democrats must defend far more Senate seats than Republicans in 2018—including several in states that Trump won—all of the party’s incumbents are currently running for reelection. The retirements of Corker and Flake, along with a Democratic victory in December’s special election in Alabama, give Democrats an outside chance at retaking the Senate majority. In the House, they’ll need to pick up a net 23 seats.

Data sources: Each district’s presidential-election results are from the Daily Kos. House and Senate election results are from the Associated Press.

Senate Republicans Retiring Outright

Bob Corker, Tennessee

2016 presidential election: +26.15 Trump
2012 Senate election: +34.6 Corker

The chairman of the Senate Foreign Relations Committee opted against running for a third term and promptly intensified his criticism of the president, whom he had praised during the election. Trump alleged that Corker “begged” for his endorsement, while Corker said it was Trump who urged him to run again.

Jeff Flake, Arizona

2016 presidential election: +3.57 Trump
2012 Senate election: +3.9 Flake

He decided to leave after a single term rather than wage what would have been a brutal fight for reelection, first in a primary against a hard-right Trump backer, Kelli Ward, and then, if he won, against a centrist Democrat, Representative Kyrsten Sinema, in the general election. Flake had lost his base in Arizona: His criticism of Trump in his recent book, Conscience of a Conservative, alienated the president’s GOP backers, while his conservative voting record put off Democrats.

Orrin Hatch, Utah

2016 presidential election: +17.9 Trump over Hillary Clinton; +23.8 Trump over Evan McMullin
2012 Senate election: +35 Hatch

The 83-year-old incumbent announced in a video message in early January that he will not seek reelection next year, creating an opening for a possible Senate bid by Mitt Romney. With seven terms under his belt, Hatch is the longest-serving Republican in the Senate. He also serves as the chairman of the Senate Finance Committee.

Thad Cochran, Mississippi

2016 presidential election: +17.83 Trump
2014 Senate election: +20.8 Cochran

Cochran, 80, announced he would resign from the Senate on April 1 due to his declining health, ending a 40-year tenure. His retirement will set off a special election in November. Republicans should be heavily favored to hold the seat, but they are wary of a divisive primary that could open the door for Democrats.

Senate Democrats Retiring Outright

Al Franken, Minnesota

2016 presidential election: +1.5 Clinton
2014 Senate election: +10.24 Franken

Under pressure from fellow Democrats, Franken announced in December he would resign “in the coming weeks” after multiple women came forward to accuse him of inappropriate sexual behavior. Most of the allegations involved Franken groping women while taking a photo. His resignation means there will be a special Senate election in 2018 in a state that Hillary Clinton barely carried in 2016.

House Republicans Retiring Outright

Paul Ryan, Wisconsin 1st district

2016 presidential election: +10.3 Trump
2016 House election: +34.77 Ryan

No retirement announcement in either party was more consequential than Ryan’s, in April. But it was not altogether surprising: The House speaker had been rumored to be considering an exit for months and had delayed filing for reelection. His departure is a huge blow to Republicans, and it could cost them a seat, as Democrats were already making a run at Ryan’s district.

Bob Goodlatte, Virginia 6th district

2016 presidential election: +24.8 Trump
2016 House election: +33.56 Goodlatte

Goodlatte was nearing the end of his third and final term as chairman of the Judiciary Committee, where he aligned with conservative hard-liners on immigration and voting rights. He advanced bipartisan legislation on criminal-justice reform, but it never reached the House floor.

Jeb Hensarling, Texas 5th district

2016 presidential election: +28.4 Trump
2016 House election: +61.21 Hensarling

Hensarling left the House leadership team in 2013 to head up the Financial Services Committee, and he passed up opportunities to make a conservative bid for speaker. His chairmanship will end because of term limits, but it was also marked by frustration: Hensarling’s proposals to wind down federal mortgage-lenders Fannie Mae and Freddie Mac, as well as his overhaul of the federal flood-insurance program, proved too conservative to pass the full House.

Rodney Frelinghuysen, New Jersey 11th district

2016 presidential election: +0.9 Trump
2016 House election: +19.15 Frelinghuysen

Frelinghuysen arrived in Washington with the Republican wave of 1994 and only reached the pinnacle of his career in 2017, when he became chairman of the House Appropriations Committee. But he has faced criticism from conservatives for voting against major GOP legislation, and he was facing the race of his life this fall in a highly competitive district. His retirement gives Democrats a seat they should pick up if they’re going to reclaim the majority.

Trey Gowdy, South Carolina 4th district

2016 presidential election: +25.7 Trump
2016 House election: +36.21 Gowdy

Despite rising quickly up the ranks of House Republicans, Gowdy had made no secret of his dissatisfaction serving in Congress, and in January he announced he would give up the chairmanship of the House Oversight and Government Reform Committee after less than a year. He’ll return to the justice system, where he served as a federal prosecutor.

Darrell Issa, California 49th district

2016 presidential election: +7.5 Clinton
2016 House election: +0.52 Issa

Issa in January became one of the most recognizable House Republicans to announce his retirement. A former chairman of the Oversight and Government Reform Committee, he served as the chief congressional inquisitor of the Obama administration for several years. Issa is annually ranked as one of the wealthiest members of Congress, having co-founded the company behind the Viper car alarm (for which he famously provided the voice). But he was in for the fight of his life to win reelection after nearly losing in 2016 in a district that Hillary Clinton carried over Donald Trump.

Joe Barton, Texas 6th district

2016 presidential election: +12.3 Trump
2016 House election: +19.31 Barton

The dean of Texas’s large Republican delegation, Barton was planning to seek a 17th term before lewd texts and photos he had sent to women with whom he had extramarital affairs leaked online. During the course of his long career in Congress, he served as chairman of the House Energy and Commerce Committee.

Lamar Smith, Texas 21st district

2016 presidential election: +10.00 Trump
2016 House election: +20.56 Smith

His is another term-limits retirement. An arch-conservative first elected in 1986, Smith likely would have had nowhere higher to go after finishing his tenure as chairman of the Space, Science, and Technology Committee, which he used to fight policies and funding to combat climate change.

Ileana Ros-Lehtinen, Florida 27th district

2016 presidential election: +19.6 Clinton
2016 House election: +9.79 Ros-Lehtinen

A former chairwoman of the Foreign Affairs Committee, Ros-Lehtinen never endorsed Trump and became one of his most vocal GOP critics in Congress. She retires after 28 years in the House. As a moderate, she voted frequently against top Republican priorities, including Obamacare repeal and the budget. Her South Florida district now becomes a prime pickup opportunity for Democrats.

Charlie Dent, Pennsylvania 15th district

2016 presidential election: +7.6 Trump
2016 House election: +19.63 Dent

As co-chairman of the moderate Tuesday Group in the House, Dent was one of his party’s most vocal critics, often voicing his frustration either with the president or the influence of the conservative Freedom Caucus in steering legislation to the right. He said the lack of a governing coalition in Congress contributed to his decision to retire after seven terms. He announced in April that he would leave office early rather than stick around for the remainder of his term.

Dave Reichert, Washington state 8th district

2016 presidential election: +3.00 Clinton
2016 House election: uncontested

A former leader of the Tuesday Group, Reichert is another moderate retiring after seven terms. Though he won his recent elections easily, his district was once one of the most competitive in the nation and could be again next year.

Pat Tiberi, Ohio 12th district

2016 presidential election: +11.3 Trump
2016 House election: +36.73 Tiberi

Whereas others on this list retired after being term-limited out of committee chairmanships, Tiberi’s decision may have more to do with a post he never won. The veteran Ohio Republican lost out to Kevin Brady of Texas in his bid to lead the Ways and Means Committee after Paul Ryan left the job to become speaker. Tiberi was a close ally of former Speaker John Boehner, and he, too, became frustrated with the dysfunction in Congress. He won’t serve out the rest of his term, choosing instead to take a job as president of the Ohio Business Roundtable early next year.

Frank LoBiondo, New Jersey 2nd district

2016 presidential election: +4.6 Trump
2016 House election: +21.99 LoBiondo

LoBiondo’s retirement after 12 terms gives Democrats a major pickup opportunity in New Jersey. First elected in the Republican wave of 1994, he broke with his party to oppose Obamacare-repeal legislation, the GOP budget, and the tax bill.

Lynn Jenkins, Kansas 2nd district

2016 presidential election: +18.4 Trump
2016 House election: +28.38 Jenkins

Jenkins’ announcement in January that she would not seek a sixth term in the House was one of the earliest and most surprising of the Republican retirements. She had served in the House leadership and was mentioned as a possible gubernatorial candidate in Kansas, but she said she would not run for any office in 2018.

Sam Johnson, Texas 3rd district

2016 presidential election: +14.2 Trump
2016 House election: +26.63 Johnson

Johnson is revered in the House for his Air Force service in both Korea and Vietnam, where he was held—and tortured—as a prisoner of war for seven years. The 87-year-old is retiring from a safe Republican seat after more than a quarter-century in Congress.

John Duncan Jr., Tennessee 2nd district

2016 presidential election: +35.4 Trump
2016 House election: +51.29 Duncan Jr.

Duncan will have served in the House for 30 years by the time he leaves next year. Though he votes with Republicans on domestic issues, he opposed the Iraq War and supports a non-interventionist foreign policy. His district should be an easy hold for Republicans.

Ted Poe, Texas 2nd district

2016 presidential election: +9.3 Trump
2016 House election: +24.26 Poe

Now in his seventh term, Poe is a former Houston judge known for ending each of his floor speeches with a variation on Walter Cronkite’s longtime sign-off, “And that’s just the way it is.” He was diagnosed with leukemia in 2016.

Dave Trott, Michigan 11th district

2016 presidential election: +4.4 Trump
2016 House election: +12.76 Trott

Trott was a first-time candidate when he won his seat in the House in 2014. He decided he preferred the private sector, however, announcing in September that he would return home after just two terms.

Ryan Costello, Pennsylvania 6th district

2016 presidential election: +9.3 Clinton
2016 House election: +14.48 Costello

Despite having served just two terms in the House, Costello is retiring rather than seeking reelection in a district that now favors Democrats after the Pennsylvania state Supreme Court threw out the existing congressional map. With the incumbent out, the 6th district is a prime Democratic pick-up opportunity.

Trent Franks, Arizona 8th district

2016 presidential election: +21.1 Trump
2016 House election: +37.13 Franks

Franks is leaving for perhaps the most unusual reason: He abruptly announced in December that he would resign after acknowledging that he had asked two members of his staff to carry his and his wife’s child as surrogates, making them “uncomfortable.” His announcement came on the same day as the House Ethics Committee said it was opening an investigation into the situation.

Blake Farenthold, Texas 27th district

2016 presidential election: +23.6 Trump
2016 House election: +23.39 Farenthold

Farenthold announced in December 2017 he would not seek a fifth term after several former staffers accused him of harassment and of verbally abusive behavior in his congressional office. He initially resisted pressure to bow out even after the House Ethics Committee opened a new inquiry into his alleged behavior. In April, he abruptly resigned from Congress altogether.

Bill Shuster, Pennsylvania 9th district

2016 presidential election: +42.5 Trump
2016 House election: +26.68 Shuster

Shuster, the chairman of the House Transportation Committee, announced in early January that he’ll spend 2018 on developing an infrastructure plan instead of running for reelection. “I thought it was the best decision for me to focus 100 percent on my final year as the chairman of the Transportation Committee, working with the president and other Democrats and Republicans to pass an infrastructure bill, which is much needed to rebuild America,” he told The Washington Examiner. Shuster first won election to the House in 2001.

Gregg Harper, Mississippi 3rd district

2016 presidential election: +24.5 Trump
2016 House election: +35.83 Harper

Harper, the chairman of the House Administration Committee, said he made the decision not to seek reelection over the holidays. “I never intended for this to be a career, and it will soon be time for another conservative citizen legislator to represent us,” he said in a statement in early January. Harper’s committee has recently received a great deal of attention as the panel charged with addressing sexual harassment in the lower chamber. The five-term congressman joins a number of other Republican committee chairmen who are stepping down.

Ed Royce, California 39th district

2016 presidential election: +8.6 Clinton
2016 House election: +14.46 Royce

The chairman of the Foreign Affairs Committee, Royce is yet another committee leader who chose retirement over a return to the back bench once his tenure with the gavel was up. Royce will finish his 13th term in 2018, and his departure creates a top pick-up opportunity for Democrats in Southern California.

Patrick Meehan, Pennsylvania 7th district

2016 presidential election: +2.3 Clinton
2016 House election: +18.93 Meehan

Meehan announced in January that he wouldn’t run for a fifth term following the revelation that he settled a claim of sexual harassment made against him by a former staffer. The House Ethics Committee—a panel of which Meehan was a member—had already begun an investigation, and the congressman acknowledged that he had developed a deep affection for the woman while denying improper behavior. Meehan resigned on April 27 and said he repaid $39,000 in taxpayer money used to settle the harassment claim. His departure opens up a strong pick-up opportunity for Democrats in what was already a competitive district.

Tom Rooney, Florida 17th district

2016 presidential election: +27.2 Trump
2016 House election: +27.57 Rooney

In February, the Florida congressman announced he would not seek a sixth term this year. “After what will be 10 years in the United States Congress representing the good people of Florida’s Heartland, it’s time to ‘hang ‘em up’ as my old football coach used to say,” Rooney said in a statement. He represents a solidly Republican district.

Dennis Ross, Florida 15th district

2016 presidential election: +10 Trump
2016 House election: +14.92 Ross

First elected in the GOP wave of 2010, Ross announced in April that he would not seek a fifth term in the House. He had made a name for himself advocating for reform of the U.S. Postal Service.

Tom Garrett, Virginia 5th district

2016 presidential election: +11.1 Trump
2016 House election: +16.69 Garrett

Garrett announced in late May that he would be leaving the House after just a single term because of his struggle with alcoholism. His retirement also came after a report that he and his wife had treated his congressional staff essentially as personal servants. The 5th district race is expected to be competitive, though it’s unclear whether Garrett’s exit will improve the GOP’s chances of holding the seat.

House Democrats Retiring Outright

Luis Gutierrez, Illinois 4th district

2016 presidential election: +68.9 Clinton
2016 House election: uncontested

Now in his 13th term, Gutierrez is perhaps the most prominent Democratic ally of immigrants in the House and has been at the center of virtually every attempt to extend a path to citizenship to those in the country illegally. In announcing his retirement in November, he anointed a possible successor in his heavily Democratic district, Jesus “Chuy” Garcia, and said he might run for president in 2020.

John Conyers, Michigan 13th district

2016 presidential election: +60.7 Clinton
2016 House election: +61.38 Conyers

First elected in 1964, Conyers was the dean of the House as its longest-serving member. But he was brought down by allegations of sexual harassment made by multiple former female staffers in his office. Conyers denied the accusations but bowed to pressure from Democratic leaders and resigned from the House in early December.

Sander Levin, Michigan 9th district

2016 presidential election: +7.8 Clinton
2016 House election: +20.51 Levin

Levin, 86, will leave the House four years after his brother, Carl, retired from the Senate. He served briefly as chairman of the Ways and Means Committee and was a top Democrat on taxes and trade policy.

Bob Brady, Pennsylvania 1st district

2016 presidential election: +61.3 Clinton
2016 House election: +64.4 Brady

A former chairman of the House Administration Committee, Brady will leave the House after 20 years. He had drawn a serious primary challenger after having been under FBI investigation for a payment his campaign made to a primary opponent in 2012.

Carol Shea-Porter, New Hampshire 1st district

2016 presidential election: +1.6 Trump
2016 House election: +1.34 Shea-Porter

Shea-Porter represents what is perhaps the nation’s quintessential swing district. It has changed parties five times in the last six elections, and Shea-Porter faced the same Republican opponent in four consecutive races. (She won twice.) With her retirement, the district is once again considered a toss-up.

Niki Tsongas, Massachusetts 3rd district

2016 presidential election: +22.8 Clinton
2016 House election: +37.53 Tsongas

Tsongas will retire after more than a decade in the House, and her district should stay in Democratic hands. She is the widow of Paul Tsongas, the former senator and Democratic presidential candidate.

Gene Green, Texas 29th district

2016 presidential election: +45.7 Clinton
2016 House election: +48.49 Green

The onetime chairman of the House Ethics Committee announced in November that he would retire after more than a quarter-century in the House. He was first elected in 1992.

Ruben Kihuen, Nevada 4th district

2016 presidential election: +4.9 Clinton
2016 House election: +4.01 Kihuen

Kihuen’s time in Congress will be brief after he faced accusations of sexual harassment less than a year into his first term. Facing calls from Democratic leaders to resign, he announced instead that he would serve out his term but not seek another one in 2018. His exit will leave a competitive open seat in Nevada that Republicans might take a serious run at picking up.

Rick Nolan, Minnesota 8th district

2016 presidential election: +15.6 Trump
2016 House election: +0.56 Nolan

This is actually the second time Nolan has voluntarily given up his seat. The Minnesota Democrat first served in the House in the 1970s and left after three terms. He returned to politics in 2012 after three decades in business, capturing a Republican-held seat. With his retirement after a total of six terms, the GOP will have a good shot at winning back the district.

Elizabeth Esty, Connecticut 5th district

2016 presidential election: +4.1 Clinton
2016 House election: +16 Esty

Esty is leaving after just three terms, having withdrawn from her reelection bid after acknowledging she mishandled allegations of abuse and harassment against her then-chief of staff in 2016. She was a vocal advocate for gun control after the Sandy Hook massacre, which unfolded in her district shortly after her first election to the House. Her district could become competitive; Esty won her first race by just three points in 2012.

House Republicans Running for Higher Office in 2018

Diane Black, Tennessee 6th district

2016 presidential election: +48.9 Trump
2016 House election: +49.29 Black

First elected in 2010, Black served this year as chairwoman of the House Budget Committee before deciding not to seek reelection and run for governor instead. With the 2018 budget finally adopted, she may leave her seat early to focus on her next campaign.

Luke Messer, Indiana 6th district

2016 presidential election: +40.3 Trump
2016 House election: +42.44 Messer

Now serving his third term in the House, Messer is facing off against fellow Indiana Representative Todd Rokita in a primary for the right to challenge Democratic Senator Joe Donnelly. He represents the seat once held by Vice President Mike Pence.

Todd Rokita, Indiana 4th district

2016 presidential election: +34.1 Trump
2016 House election: +34.12 Rokita

Rokita entered Congress one term before Messer. He made a brief bid for governor in 2016 after Pence was named as Donald Trump’s running mate, but he was able to retain his House seat after Republicans picked Lieutenant Governor Eric Holcomb. He won’t have that luxury if he loses the Senate race because the primaries for the Senate and House are on the same day.

Steve Pearce, New Mexico 2nd district

2016 presidential election: +10.2 Trump
2016 House election: +25.48 Pearce

After serving two separate stints covering seven terms in the House, the conservative Pearce is running to succeed Susana Martinez as governor of New Mexico. Republicans remain favored to keep his House seat.

Raul Labrador, Idaho 1st district

2016 presidential election: +38.3 Trump
2016 House election: +36.36 Labrador

Labrador defeated a GOP establishment-backed candidate in a 2010 primary before beating a centrist Democratic incumbent during the Tea Party wave that November. His decision to run for governor may be a blessing for GOP leaders, as he was a frequent conservative critic and member of the House Freedom Caucus during his tenure. Republicans should hold his seat easily next year.

Jim Renacci, Ohio 16th district

2016 presidential election: +16.6 Trump
2016 House election: +30.66 Renacci

One of the wealthiest members of Congress, Renacci originally announced plans to leave the House after four terms to run for governor of Ohio. But in January he decided to run for Senate instead after a leading Republican candidate, Josh Mandel, withdrew from that race.

Lou Barletta, Pennsylvania 11th district

2016 presidential election: +23.8 Trump
2016 House election: +27.34 Barletta

Barletta was a Trump Republican before Trump and became one of the first to endorse the president’s campaign. A longtime crusader against illegal immigration, his Senate candidacy challenging Democratic incumbent Bob Casey will be a test of Trump’s brand in a formerly blue state that the president flipped red in 2016. Though it was held by a Democrat until Barletta won it in 2010, the 11th district is not currently expected to be competitive in the 2018 general election.

Kristi Noem, South Dakota at-large

2016 presidential election: +29.79 Trump
2016 House election: +28.21 Noem

Noem defeated Democrat Stephanie Herseth Sandlin in one of the closest races in the 2010 Republican wave. She’s giving up her House seat to run for governor, and Democrats will have a tough time winning it back.

Evan Jenkins, West Virginia 3rd district

2016 presidential election: +49.2 Trump
2016 House election: +43.91 Jenkins

Jenkins knocked off one West Virginia Democrat, Nick Rahall, to win his House seat in 2014. He’ll try to beat another, Senator Joe Manchin, in 2018. As with many of the seats Republicans are giving up to run for higher office, the 3rd district is less favorable to Democrats than it used to be.

Ron DeSantis, Florida 6th district

2016 presidential election: +17.0 Trump
2016 House election: +17.13 DeSantis

A conservative in his third term, DeSantis announced in January he would run for governor, not Congress, in 2018. His decision came just a couple weeks after Trump offered him an unexpected endorsement in a pre-Christmas tweet. DeSantis won the Republican gubernatorial primary in August and then resigned his House seat in early September to focus on the general election.

Martha McSally, Arizona 2nd district

2016 presidential election: +4.9 Clinton
2016 House election: +13.92 McSally

McSally launched her long-expected Senate campaign in January for the seat Jeff Flake is vacating. Serving her second term in the House, she had become famous as the first American woman to fly in combat during the 1990s. Republicans leaders see her as the best candidate to hold the Senate seat, but her departure gives Democrats another strong pick-up opportunity in the House.

Marsha Blackburn, Tennessee 7th district

2016 presidential election: +39.3 Trump
2016 House election: +48.71 Blackburn

Blackburn is leaving a safe Republican House seat after eight terms to run for the Tennessee Senate seat Bob Corker is vacating. With the support of conservative groups, she appears in solid shape to win the GOP nomination after Corker briefly reconsidered his decision, but she’ll face a touch general-election matchup against Phil Bredesen, the state’s former two-term Democratic governor.

Kevin Cramer, North Dakota at-large district

2016 presidential election: +36.4 Trump
2016 House election: +45.46 Cramer

The third-term congressman declared his candidacy to challenge Democratic Senator Heidi Heitkamp in February, barely a month after announcing he would forgo the race. Cramer’s Senate run opens up his at-large House seat, which should stay in Republican hands this fall.

Jim Bridenstine, Oklahoma 1st district

2016 presidential election: +28.7 Trump
2016 House election: Uncontested

Bridenstine didn’t run for higher office after three-and-a-half terms in the House, but he was picked in 2017 by President Trump to serve as the next administrator of NASA. His nomination languished in the Senate for months, but his confirmation on a narrow party-line vote in April created another vacancy and open seat in November. Republicans should easily hold this conservative district.

House Democrats Running for Higher Office in 2018

Kyrsten Sinema, Arizona 9th district

2016 presidential election: +16.3 Clinton
2016 House election: +21.88 Sinema

Sinema announced her candidacy for the Senate before Flake decided to retire. A member of the centrist Blue Dog Coalition, she has occasionally voted with Republicans on health care, taxes, and border security. She’s also the first openly bisexual member of Congress. Though Sinema’s first election in 2012 was very close, her district has trended more Democratic in the years since.

Jared Polis, Colorado 2nd district

2016 presidential election: +21.3 Clinton
2016 House election: +19.72 Polis

Another of Congress’s most wealthy members, Polis is running for governor after five terms in the House. The district includes Boulder and is considered a safe Democratic seat.

Tim Walz, Minnesota 1st district

2016 presidential election: +14.9 Trump
2016 House election: +0.76 Walz

Walz’s decision to run for governor of Minnesota after six terms in the House gives Republicans one of their best pickup opportunities. He won his 2016 race by only about 2,500 votes.

Beto O’Rourke, Texas 16th district

2016 presidential election: +40.7 Clinton
2016 House election: +75.75 O’Rourke

O’Rourke won his House seat in 2012 after defeating a longtime Democratic incumbent, Silvestre Reyes, in a primary. He’ll have an even tougher challenge in 2018: knocking off Ted Cruz in a Senate race. His district in El Paso, meanwhile, figures to remain blue.

John Delaney, Maryland 6th district

2016 presidential election: +15.1 Clinton
2016 House election: +15.89 Delaney

The former entrepreneur is unique among all of the congressional retirees. Delaney is not leaving to run for Senate or governor—he’s already running for president in 2020. Despite his considerable wealth, he’s a heavy long-shot, but he’s hoping a super-early start will help. Delaney’s ouster of Republican Roscoe Bartlett in 2012 was aided by Democratic gerrymandering, and the district continues to favor Democrats as an open seat in 2018.

Jacky Rosen, Nevada 3rd district

2016 presidential election: +1.00 Trump
2016 House election: +1.27 Rosen

Rosen had barely started her first term in the House this year when she announced she would challenge incumbent Republican Senator Dean Heller in 2018. Though she has the support of Harry Reid’s powerful political operation, the race is a risk for Democrats, since her exit creates an opening for Republicans to take back a seat they held until Rosen’s victory in November.

Colleen Hanabusa, Hawaii 1st district

2016 presidential election: +32.6 Clinton
2016 House election: +49.15 Hanabusa

Hanabusa held this seat for four years before giving it up for a failed bid for Senate. After a year back in the House, she’s leaving again to run for governor. Though the seat was briefly held by a Republican in 2010, it’s a solidly Democratic district.

Michelle Lujan Grisham, New Mexico 1st district

2016 presidential election: +16.5 Clinton
2016 House election: +30.29 Grisham

Lujan Grisham won her first race for the House and is now running for governor. She is currently serving as chairwoman of the Congressional Hispanic Caucus.

Keith Ellison, Minnesota 5th district

2016 presidential election: +60.3 Clinton
2016 House election: +46.85 Ellison

Ellison decided in early June to run for Minnesota attorney general instead of reelection to the House. A former chairman of the Congressional Progressive Caucus, he will retain his post as vice chairman of the Democratic National Committee.
