So Biden didn’t withdraw this week. He doubled and tripled down. Anyone still think he’ll step down?
Not on his own. And not unless he either has a sudden health crisis or falls down the stairs of Air Force One (accidently, of course).
Lots of dems think it's already too late in the game to suddenly replace him, so they support him. Personally, I wouldn't mind seeing him stay in the race, continue showing us entertaining gaffes and missteps which make his supporters gasp, and the dems divided against each other about whether he should stay or go.
From this point, the longer he stays in before dropping out, the harder it will be for the dems to win in November.
Maybe he'll drop out in October as an "October Surprise".
