Mr. Trump no doubt wanted to project strength and rattle Mr. Biden, but he did so by interrupting him so much that he wouldn't let Mr. Biden talk long enough even to make a mistake. The President bounced from subject to subject so frequently that it was hard to figure out what he hoped to say beyond that Joe Biden is controlled by the Democratic left. Even when moderator Chris Wallace asked a question that played to the strengths of his record—such as on the economy—Mr. Trump couldn't stick to the theme without leaping to attack Mr. Biden.
The former Vice President wasn't much better, interrupting nearly as much. And for the candidate who says he wants to bring people together, he was ready with his own name-calling. He called Mr. Trump a "racist," a "clown," and told him to "shut up, man." He spun out falsehoods as fast as the President, notably in asserting that 100 million people would be vulnerable to losing their health insurance due to pre-existing conditions. The Obama Administration set up a special fund for pre-existing conditions in the transition to ObamaCare, and the takers were only in the thousands. Mr. Trump didn't know enough to be able to rebut him.

The truth is that Mr. Biden hasn't offered anti-virus policies that are much different than Mr. Trump's, except for a mandate to wear masks, which he has since walked back. His indictment is mainly about Mr. Trump's temperament and narcissism, which Mr. Trump reinforced with his interruptions and "you're worse" taunts. Mr. Trump succeeded again in making his pandemic policies sound worse than they are.
The benign explanation for the President's performance is that like other incumbents in their first debates he was overconfident and underprepared. A less benign view is that he grew flustered as the debate went on and ...
