I don’t think their strategy is to force him out of office. They wouldn’t dare. What they are counting on is a Muller type investigation 2.0 even more elaborate than the first, more tv coverage non stop that would run through election cycle 2020 and turn public opinion so much against him that he gets voted out of office. Trump understands this and has made it clear he is not going with it.
That sounds more plausible.
IF by a long shot it works in sending him down in 2020 it should still be a war.
We already watched a coup attempt without doing anything.
It’s all insanity.
