I've heard that, but New Years & all. I don't know what he does at 3am when he starts the tweets, but if he says something monumentally stupid, they will, Republican & Democrat alike, pounce on him & try to remove him.
Democrats would much rather have Powell than Trump. Their Electoral Slate crossed party lines to cast Electoral votes for him. That would sit well with Never Trump Republicans and probably most of main stream America given the alternative. CNN is pushing hard that this is not partisan, but a serious attack on the USA that crosses party lines.
They will ratchet this up the closer we get to the counting, adding fuel wherever possible. All they would need to do is declassify a Trump collusion with Russia (that would ultimately prove untenable), preferably of the Trump Campaign in direct communication with the Kremlin or one of the sons released on January 5th or so and they could probably pull it off.
I wouldn't put it past them. They could also try to delay the Inauguration leaving our current illustrious leader in place to deal with the crisis until this affair was fully investigated by Congress if they find a scrap of paper tying Trump to Russia or Ivanka has a nesting doll.
I'll believe Trump will be president when I see him sworn in.
