There is too much sketchy shit going on, so I don't think I have a tin foil hat. Here's my theory.

35. I think what is happening is mostly from Democratic elites who want a different choice

They KNOW they will vote against Trump or any MAGA selected alternative. I think there are largely 2 groups here.

One group consists of many who claim that Biden only intended to have one term as a transitional President and they feel he should not have run for reelection. However, the time to create this pivot was before the primaries and no credible candidate ran against him. Those with media power used the bad debate performance for a full throated effort to get Biden to stop his campaign, notably the NYT. That is the only way another person could get the nomination.

After 2 weeks of incessant reporting that Biden needs to go and is too old to be running, the polls have moved against him which is not surprising as that has been most of the "news". This leads to a second group joining the first who worry the campaign is in a terminal downward spiral and nothing is as important as stopping Trump.

Some have asked why not go after Trump in the same way. My guess is his stepping down does not get them the perfect candidate to vote for.
