The Memo: The debate that changed everything

ATLANTA — Never before has a debate transformed a presidential race so utterly.

The idea of replacing President Biden as his party’s 2024 nominee has become Topic A in national politics; former President Trump has advanced from a slight to heavy favorite in November’s election; and the collective blood pressure of the Democratic Party has gone through the roof.

It all happened in about 90 minutes on a debate stage here on Thursday night.

For Biden, it really was that bad.

“The worst performance in debate history” was the verdict of one Democratic strategist texting with this reporter while the clash at the CNN studios was still happening.
