President Donald Trump arrived at the first debate with a theory and a plan. The theory was that American voters crave dominance, no matter how belligerent or offensive. The plan was to hector, interrupt, and insult in hopes of establishing that dominance.

His theory was wrong, and his plan was counterproductive…

Trump yelled, threatened, interrupted—and changed nothing. All he did was confirm the horror and revulsion of the large American majority that has already begun to cast its ballots against him.

Correction: Trump did one thing. On the Cleveland stage, Trump communicated that he will seize any opportunity to disrupt the vote and resist the outcome. He communicated more forcefully than ever that the only security the country has for a constitutional future is that Biden wins by the largest possible margin.
