They are drinking the Kool-Aid, a few late electoral wins in Virginia and them believing their own propaganda about impeachment has them giddy in anticipation about 2021 and a chance to make this country a combination Sweden\England and a little communist China thrown in.
This really is Trump's election to lose, they are bating him to react. He needs to keep it up and go on the offensive. When he has one Democrat target to go after Warren\Sanders\Buttigeig\Clinton\Bloomberg it's going to be epic. I do think a 1972 or 1984 style blowout is not possible, too much institutional voter fraud and demographic changes in 30+ years. But we can hit 300+ EVs. What I will put solid money down on is we flip the House and keep the Senate. I predict they pass impeachment over the holidays, Turtle in a few weeks votes on it and that is that. Then the campaign ads paid for big tech, big green and big Evil(Soros). I am sure Trump has kept his powder dry with his own series of frog marches, indictments and humiliations coming for the treasonous slime.
