They could JFK Biden, which I think they're spiteful enough to do. That would solve some of their problems, notably the fractious party, especially if they're able to pin it on Trump supporters somehow. I'm sure the FBI has a glownigger on hand that can get the job done.

Who else is there?

Big Mike. He's the obvious choice to replace Kamala without triggering a spat over DIE. As I've said elsewhere there's no one more oppressed than a black faggot in a dress.
