Ousting a demagogue with the loudest megaphone in the land is not an easy undertaking. Trump’s opponents had to overcome an unprecedented stream of disinformation and falsehoods from the president, even as his party normalized the assaults on truth, on facts, on science, on expertise. Trump’s opponents were up against a strongman who used the Justice Department, diplomats and the intelligence community to harass political opponents, who used federal police to suppress public demonstrations, who engaged in a massive campaign of voter intimidation and suppression, and who used government powers for political advantage: enlisting government employees to campaign for him, sabotaging postal operations, putting his name on taxpayer-funded checks, using the White House for a party convention. And Trump’s opponents had to contend with a Fox News cheering section and social-media landscape that insulated millions from reality.
