@Walter Hinteler,
This you can't really blame on Trump, this is more than likely one of the shameful advantages the "resistance" in the WH sees as something they got to continue under Trump.
In my opinion, they are waiting for mid-terms to see if democrats win control of the house and senate. (I haven't heard or read where we have a chance in the senate, but, I haven't really looked.) They probably know republicans are not going to ruin their election chances with Trump's base who will make any such "resistance" against Trump look like the mild chastisement it is in the case of impeachment. (Trump called it right, there will be violence but not by the left.)
If democrats win the house and senate and remove Trump from office, Pence will still be there to carry out all the deregulations, tax cuts for the rich, draconian immigration policies they like and they would be rid of one big headache. We would in fact be doing them a favor. Nevertheless, I think it is the right thing to do.
If they don't, (Dems win) who knows really what is going to happen? I am not sure after mid-terms what republicans will do. It will depend if something becomes so bad and obvious I guess. I somehow doubt democrats will win both the house and senate, we have a chance at the house I think I have read. We (as in the US) might just have to keep on with the way things are now until Trump finishes out his term. It would just be beyond shameful and horrible if he actually gets elected in this country again. But I wouldn't be surprised.
