Sounds crazy to do it so soon, but I'm imagining from their perspective ... Why not?

There is nothing more they need or want from his withering carcass. They did all of the rhetorical ground work already. Joe even said he wanted a VP who would be ready to take over on day one... Something like that.

Another time he said he might just get sick of some disease and have to hand it over. Just paraphrasing.

So they can flop him out there and have him ready a simple fluffy resignation speech. Then the media will lavish praise and shift the narrative to the historic rise of Kamala.

... But more likely it'll just be more invented words and racist blunders.
