At dawn this morning, workers loaded couches and tables into a moving truck parked outside the West Wing. Men wearing white coveralls and carrying roller brushes and paint cans walked across the north driveway. Inside the White House, pictures of the 45th president had been removed from the walls. Only the hooks remained, ready for a new set of portraits of the 46th.

A lone Donald Trump press deputy, Judd Deere, sat in his small office, writing a note on a piece of stationery to whoever would be taking over his desk in a few hours. Deere was attempting to describe what it’s like to work in the building. When I looked in at noon, after the Trump presidency had officially ended, he was gone, his desk cleared. Even the magazine racks hanging on the wall had been emptied.

Donald Trump’s chaotic final days in the White House could present President Joe Biden with a historic opportunity to broaden his base of public support and splinter Republican opposition to his agenda.

Recent polls have repeatedly found that about three-fourths or more of GOP voters accept Trump’s disproven charges that Biden stole the 2020 election, a number that has understandably alarmed domestic-terrorism experts. But in the same surveys, between one-fifth and one-fourth of Republican partisans have rejected that perspective. Instead, they’ve expressed unease about their party’s efforts to overturn the results—a campaign that culminated in the January 6 attack on the Capitol by a mob of Trump’s supporters.

President Donald Trump has long exulted in superlatives. The first. The best. The most. The greatest. “No president has ever done what I’ve done,” he boasts. “No president has ever even come close,” he says. But as his four years in office draw to an end, there’s only one title to which he can lay claim: Donald Trump is the worst president America has ever had.

In December 2019, he became the third president to be impeached. Last week, Trump entered a category all his own, becoming the first president to be impeached twice. But impeachment, which depends in part on the makeup of Congress, is not the most objective standard. What does being the worst president actually mean? And is there even any value, at the bitter end of a bad presidency, in spending energy on judging a pageant of failed presidencies?

I’ve been thinking about Barbara Tuchman’s medieval history, A Distant Mirror, over the past couple of weeks. The book is a masterful work of anti-romance, a cold-eyed look at how generations of aristocrats and royalty waged one of the longest wars in recorded history, all while claiming the mantle of a benevolent God. The disabusing begins early. In the introduction, Tuchman examines the ideal of chivalry and finds, beneath the poetry and codes of honor, little more than myth and delusion.

Knights “were supposed, in theory, to serve as defenders of the Faith, upholders of justice, champions of the oppressed,” Tuchman writes. “In practice, they were themselves the oppressors, and by the 14th century, the violence and lawlessness of men of the sword had become a major agency of disorder.”

A few days after Christmas, Molly Hering, 14, and her brother, Sam, 12, got their first shots as part of the Pfizer COVID-19 vaccine trials for kids. Their mom had heard about a clinical trial being conducted at Cincinnati Children’s Hospital, and Molly told me that she’d agreed to join because she wanted to contribute to the vaccine-development effort.

Molly and Sam’s dad was recently hospitalized with COVID-19. (He recovered.) Both kids have spent most of the past year dealing with Zoom school and its attendant technical glitches. Molly finally went back to in-person ninth grade this month, but masks and social distancing are required at school. Like everyone else, she’s looking forward to the end of the pandemic. “I’ll finally be able to go to school normally,” she said.

Here’s a little quiz. Take a look at the picture of the photo above, which shows the newly redecorated Oval Office that is occupied by Donald Trump. What’s unusual in this scene?

As a helpful hint, here’s a close-up of the area you should be looking at:

Is it the Remington bronze statue known as “The Bronco Buster” on the right, which many presidents have displayed? No. The portrait of Andrew Jackson just above the statue, which has survived the departure of Jackson-fan Steve Bannon? No. The bust of Lincoln, on the left? Beneath the portrait of Jefferson? No, and no—although it would be instructive to know the thoughts of the third and the 16th presidents as they gaze on the 45th.

“How to Build a Life” is a column by Arthur Brooks, tackling questions of meaning and happiness. Starting today, the column will be published weekly on Thursday mornings.

I am an inveterate scorekeeper. I can go back decades and find lists of goals I set for myself to gauge “success” by certain milestone birthdays. For example, in my 20s, I had a to-do list for the decade, the items on which more or less told the story of a penniless musician who had made some dubious choices. It included quitting smoking, going to the dentist, mastering my pentatonic scales, and finishing college. (I hit them all, although the last one mere days before my 30th birthday.)

There is nothing unusual about this tendency to keep score. Google “30 things to do before you turn 30” and you will get more than 15,000 results. Researchers writing in the journal Psychological Science a few years ago observed that people are naturally motivated toward performance goals related to round numbers, and birthdays in particular can often act as landmarks to motivate self-improvement. We naturally seek outside sources of quantitative evidence of our progress and effectiveness—and, thus, our happiness.

As I sat in my Capitol Hill office two weeks ago, watching a violent mob storm the symbol and seat of our democracy, I was reminded of my distant past. As a child, I saw my birth country of Somalia descend from relative stability into civil war, overnight. The spaces where people felt most secure—their homes and workplaces—suddenly became battlegrounds, torn by gunfights and bombings. Violent targeting of political leaders—once unheard-of—became commonplace.

I never expected to experience a direct assault on democracy in the United States, one of the oldest, most prosperous democracies in the world.

But if there is any lesson we can draw from the past four years, it is that it can happen here. If we are to address the root causes of this insurrection, we have to understand, deep within ourselves, that we are human beings like other human beings on this planet, with the same flaws and the same ambitions and the same fragilities. There is nothing magical about our democracy that will rise up and save us. Building the democratic processes we cherish today took hard and dedicated work, and protecting them will take the hard and dedicated work of people who love this country.

For most of 2020, the coronavirus that causes COVID-19 jumped from human to human, accumulating mutations at a steady rate of two per month—not especially impressive for a virus. These mutations have largely had little effect.

But recently, three distinct versions of the virus seem to have independently converged on some of the same mutations, despite being thousands of miles apart in the United Kingdom, South Africa, and Brazil. (A mutation is a genetic change; a variant is a virus with a specific set of mutations.) The fact that these mutations have popped up not one, not two, but now three times—that we know of—in variants with unusual behavior suggests that they confer an evolutionary advantage to the virus. All three variants seem to be becoming more common. And all three are potentially more transmissible.

As President Joe Biden takes office, his administration will get to work reversing some of the Trump administration’s most controversial and destructive policies, including the elimination of key environmental protections, the creation of new immigration restrictions, and the sabotage of the Affordable Care Act.

After the Georgia runoffs, it’s tempting to think that a Democratic Congress could just legislate these policies away. But the Senate filibuster is likely to remain intact for now, effectively giving Republicans a veto over legislative efforts to undo President Donald Trump’s regulatory legacy.

Nor can President Biden reverse the damage just by signing a fat stack of executive orders. Instead, the law requires federal agencies to follow certain procedures—many quite persnickety—when they make changes to government policy. And reversing Trump-era policy will be all the more difficult because that administration used its remaining days in office to create additional procedural obstacles to insulate its decisions from reversal.
