Here's a weird scenario....

Although the 25th Amendment can be used to remove Biden from the office of the president, it can not be used to prevent him from becoming the Democratic nominee.

So his cabinet can remove him - obviously unwillingly on his part or the 25th Amendment wouldn't be needed.  And if he's unwilling to resign as president then he's obviously going to be unwilling to advise delegates pledged to him to nominate someone else.  So he would be the Democratic nominee and could conceivably (by hook or by crook) win the presidency again.

So then what does the cabinet do?  Remove him again when he is sworn back in in January?  I don't think so.  I think they would keep him in that scenario.  Any Dems that want to remove Biden only want to do so because they're afraid Trump will win in November.  But if Biden wins, I would think they would keep him.
