Nate Silver says 'underrated' probability Biden isn't nominee

crazy to think he could serve four more years
Polling guru's forecast before Biden's troubled debate favored Trump to win presidency
Polling expert Nate Silver argued Monday that President Biden's debate performance has put him at serious risk of not being the Democratic Party's nominee in November and called it one of the "craziest asks" in political history for him to seek a second term.

"I think the probability that Biden isn't the nominee on Nov. 5 is closer to underrated than overrated," Silver wrote Monday in a thread on X.

Silver added that Democrats face many risks maintaining Biden as the head of the party ticket. Biden, already the oldest president in American history, would be 86 by the end of a second term if re-elected. Ronald Reagan, who held the record before him, was 77 when he left office in 1989.
