I also think there is a strong possibility that they will find Trump violated money laundering rules or tax rules. I'm guessing he cut corners; it won't just be technical, but it won't be as blatant as it was for Manafort. It will be somewhere in between.
That's all just a prediction. We haven't seen the evidence yet.
I also think it is relevant that Trump has NO friends. He eventually has fall outs, even with best buddies like Bannon. When it comes time to vote, there aren't going to be more than a handful of Sens and Reps who care about the individual. They will consider their own political interests and vote accordingly.
As I write this a mouse, or something bigger, just ran across my basement. Better get on that ...
