A nightmare began with Donald Trump’s victory in November 2016. It has just been extended indefinitely with his narrow loss and wild allegations of electoral fraud.

In his 2016 campaign, Trump prospered by challenging the legitimacy of America’s political and economic system, arguing that it was rigged to benefit a few elites. Over the next four years, he demonstrated, in diverse and ingenious ways, his profound unfitness for high office.

Still, nearly 70 million voters plainly wished to keep him in the White House, confirming that Trump’s self-presentation as an outsider despised by political and media elites had gained broad and enduring acceptance.
