Let's see... the whole impeachment case rests on whether Trump demanded Ukraine investigate a suspicious deal involving the Former VP's son. First, they haven't proved it. Second, even if they prove it, they will have to convince the public that it is a crime (most will say "so what?"). Third, even if they convince the public it is a crime, they will have to convince them that it rises to an impeachable offense - otherwise it will look like they are overturning an election because the president jaywalked once.
So far as the election, the Dems are already eating their own. Sanders gets a major boost from Joe Rogan, and the Clinton side immediately paints likable Joe as a white supremacist and transphobe.
Thank god the fascists are hopelessly inept. Gives me hope or the USA.
I hope their next screw-up will be to call Bolton as a witness. That will open the door for more witnesses, like Biden and Schiff. Be fun to watch. But I don't think even the Dems are that stupid.
