Trump celebrated what may be the extrajudicial killing of Michael Reinoehl, an antifa activist wanted in a fatal shooting, but such killings weren’t the norm. He put children in cages, but was pressured to let them out. And in the end, he lost an election and will have to leave.

The damage he’s done, however, may be irreversible. On Twitter, Robin argued, correctly, that George W. Bush, far more than Trump, changed the shape of government, leaving behind the Patriot Act and the Department of Homeland Security. Most of Trump’s legacy, by contrast, is destruction — of even the pretense that the law should apply equally to ruler and ruled, of large parts of the Civil Service, of America’s standing in the world. (If mainstream liberals are more deeply horrified by Trump than some leftists, it could be because they maintain greater romantic attachments to the institutions he’s defiled.)

Most consequentially, Trump has eviscerated in America any common conception of reality. Other presidents sneered at the truth; a senior Bush official, widely believed to be Karl Rove, famously derided the “reality-based community” to the journalist Ron Suskind.

But Trump’s ability to envelop his followers in a cocoon of lies is unparalleled. The Bush administration deceived the country to go to war in Iraq. It did not insist, after the invasion, that weapons of mass destruction had been found when they obviously were not. That’s why the country was able to reach a consensus that the war was a disaster.

No such consensus will be possible about Trump — not about his abuses of power, his calamitous response to the coronavirus, or his electoral defeat. He leaves behind a nation deranged.

The postmodern blood libel of QAnon will have adherents in Congress. Kyle Rittenhouse, a young man charged with killing Black Lives Matter protesters, is a right-wing folk hero. The Republican Party has become more hostile to democracy than ever. Both the Trump and Bush presidencies concluded with America a smoking ruin. Only Trump has ensured that nearly half the country doesn’t see it.

In May, Samuel Moyn predicted, in The New York Review of Books, that if Biden won, fears about American fascism would dissipate. Complacent in their restoration, he wrote, those who warned of fascism “will cordon off the interlude, as if it was ‘an accident in the factory,’ as Germans after World War II described their 12-year mistake.”
