I don't think so.
Too many big names opposing Biden.
Too many big names waiting in the wings (Hillary, Michelle, Newsome).
I'd say there's a 50/50 chance of an upset at the Democratic convention this summer. Especially if the left stages 1968 style riots against "Genocide Joe."
What proof do you have that Michelle Obama is waiting in the wings? Everything I’ve read is that she has zero interest, has said so repeat repeatedly, and is doing absolutely nothing to promote this. If you know, otherwise, please share otherwise it’s an idiotic distraction and they really don’t know why people keep bringing her up when she’s a nobody at this point.
