Bad Idea. If the Islamocrats manage to impeach DJT they will get their wish and the US will come apart at the seams. At this point in the narrative, the smartest thing they could do is shut the fuck up and focus on 2020.

I personally don't think they can do it, but I've been wrong before (once, a long time ago)
Democrats have started ratcheting down the impeachment talk. They'll probably make impeachment noises for election coverage.
