I think the ball is rolling in the direction of him dropping out. He says he's staying but nothing he's done since the debate has proven that he'd capable of running effectively. He sounded bad in the ABC interview, again. And given the clips of Harris that came out today from Essence Fest, with her articulating and arguing effectively...it's hard for folks to argue Biden can do this better.
My fear is the race aspect. The democrats and apologists who are pretending like this is a coup or media-driven assault are going to hurt Harris if she ends up as the nominee. They're gonna blame her and she will lose some white support. Granted she will gain some non-white support but it could kill her chances.
