 The Biden campaign says the president dropping out of the race would only lead to weeks of chaos, infighting, and would pave the way for Donald Trump to win. Their spin is that, yes, the debate was very, very bad, but at least the polling so far shows it didn't really change the minds of voters very much. And I'm also told, John, that if public pressure builds for the president to step aside, well, he may only dig in his heels more to prove them wrong.
