If the Democrats don't win both the presidency and the house, we won't be able to find out shit. And unless the Democrats win a super majority in the senate there will be nothing that they can do about it.
Ya got the house already and the margin is expected to increase, I figure Trump is done (but make fucking sure) and it really looks like a simple majority in the senate with Moscow Mitch in serious trouble himself, just getting rid of him will do a lot. If not a simple senate majority can investigate him, expose him, publicly humiliate him and sic a grand jury on him and is corrupt wife. That's how things seem to stand right now, but they are about to get much worse for the republicans where the rubber meets the road, back home, people will be dying and mainstreet fucked, small businesses bankrupt. Nancy is no fool, she is wise, I doubt she will miss the chance to at least hold impeachment investigations after oversight and Donald will most assuredly withhold documents and witnesses or try to impede congress and commit other impeachable offenses, it's a given, aside from the core charges of dereliction of duty and criminal negligence causing mass death. What would a late summer impeachment trial look like, with Donald being an asshole over something that's killing thousands of Americans a week and withholding vital government documents from oversight in a time of extreme national crises, one of his creation?
This is what is in store for the republican senate and they know it, the democrats would be nuts not to do him, but Nancy knows best. The damage to the GOP is already done and going into the election headless is a lot like what America is going through now, it's leaderless, ya might as well not have a federal government, Donald fucked it up that badly.
