He has "yes" men, incompetents and closet marxists. His level of narcissisisam cannot tollerate anything else, his personality is too weak. He is augering in mentally, I think, and will be as nutty as Nixon was just before he resigned. The difference is he'll be insisting WE are the insane ones. Nixon, after all, recognized the paranoia resided in him.
I pray that before this happens, Biden will have the grace to resign, and someonec half way competent will replace him as VP. The only possibly worse than Biden would be Ron Paul. Offhand, I can't think of any Dem who'd make a good President at this moment in history.
