Honestly, given the amount of news that this is getting, I’m starting to think that a decision has already been made, and that the Dems are either:
Waiting for it to blow over, and for Biden to stay and fight
A transition candidate has been picked, and it’ll be either Harris or another candidate to announce themselves with an immediate campaign.
The former seems like a terrible idea. Before the debate Biden was “fine” as a candidate, and debates don’t really affect much in terms of voting intention - but dragging this out and staying on just looks bad with Trump having the (I can’t believe I’m writing this) near-assassination high after his convicted felon low.
Depending on the candidate, the latter could be a fantastic move. I’m not convinced that Kamala Harris could beat Trump, but a double-ticket of someone like AOC with either Biden or Harris as VP could be a winner. Play things coy, have Biden come out right at the end, say he’s staying on…as a VP to your new candidate, and start flooding the news and socials with the new candidate. Trump will lose his shit because the news is no longer on him.
