Why Biden Wanted to Debate Trump Early, and Why Trump Said Yes

Tens of millions of dollars of advertising has not changed President Biden’s polling deficit. Donald J. Trump’s criminal trial has not altered the race’s trajectory. And Mr. Biden’s significant cash and infrastructure advantages have yet to pay political dividends.

So on Wednesday, the one weekday Mr. Trump is not confined to a courtroom, the Biden campaign shook up the race, publicly offering to bring forward the first presidential debate by three months. The move was meant to jolt Americans to attention sooner than later about their consequential choice in 2024. Mr. Biden’s advisers have long believed that the dawning realization of a Trump-Biden rematch will be a balm for the president’s droopy approval ratings.

The Trump team swiftly accepted. And Mr. Trump proceeded to do Mr. Biden the favor of lowering expectations for his performance, writing on social media that his rival was “the WORST debater I have ever faced.” The post was a preview of the insults to come, with Mr. Trump accusing the president of being unable to “put two sentences together” and calling him “crooked” three times.
