The willingness of the GOP to kowtow to Trump makes me wonder just what he would have to do for them to begin impeachment proceedings. Few have spoken out against him, and the never Trump folks in the Senate, like Sasse and Flake, have voted for each of his Cabinet nominees. Most of the House are in such gerrymandered districts they fear nothing from the left, only being primaried. I've said this on other threads, but I don't think much will happen until rank-and-file Republican voters finally wake up and realize they've been conned.
Price's seat is up in a special election in April; that may be the first real indicator of a sea change.
