 Bill Clinton or Barack Obama publicly stepping forward. I think Biden can ride it out. He's a stubborn man. They're holding their tongue for now, but there's indications that that might last or not, right? And that's going to be a large part depending on how does he do in the news conference tonight. If he does fine in the news conference tonight, and the bar is pretty low for Joe Biden to do fine, then it buys him more time. If he does fine again with Lester Holt, it buys him more time.
