A democrat may win the next election, Stanley. But chances are pretty good that it won't be Dementia Joe. The media is already starting to turn on him, and the public had little to no faith in him to start with.
He did his good deed by beating Trump, so once the swamp realizes they not only have no need for him, but that he's an unpredictable, senile, doddering old fool who will likely gaffe us into a war with Russia or China, they'll bury him, too.
