Republican Rep. Candice Miller announced her retirement Thursday, the latest in a string of congressional departures that have sapped the once-powerful Michigan delegation of seniority and power in the Capitol.

Miller, the only female committee chair in the House of Representatives, runs the chamber's Administration Committee. And she's following four high-ranking Michigan members out the door after a string of retirements in the past two years.

Last term, House Ways and Means Committee Chairman Dave Camp and Intelligence Committee Chairman Mike Rogers, both Republicans from Michigan, stepped aside and decided not to run for reelection. So too did Rep. John Dingell, the longest-serving member of the House and the Democratic ranking member emeritus on the Energy and Commerce Committee. Sen. Carl Levin, then the chairman of the Senate Armed Services Committee, also decided to retire in 2014.

Together, the three House members accrued 48 terms of House seniority, while Levin had been in the Senate for 30 years. Miller was first elected in 2002.

Michigan still has some committee clout. Rep. Fred Upton chairs the House Energy and Commerce Committee—but he's been at that post for three terms, the GOP's self-imposed cap on committee chairmanships. And with veteran members retiring en masse, the state's era of outsized Capitol Hill influence is ending.
