NoM, Biden was never at the top of his wits. He’s always been Slow Joe. But senility happens; some people get it and some don’t, and it’s clear to anyone who pays attention that he has it.
Why would anyone have to be “respected in the Democrat Party” to tell Biden what to do? if it comes to it, the 0bama machine will simply give him the choice between resigning or having a funeral. They don’t have to be respected to do that, just powerful. The only resistance would be from “Dr” Jill, who has visions of being another Edith Wilson, and from Harris whose presidential ambitions would be cut short by a replacement candidate.
