I think everyone in the GOP is surprised at how nutty all the MAGAts are. Anyone who challenges their God Emperor gets shouted at, SWATted, bad shit mailed to them, and generally slandered.
It even has affected the judges. Look at the one in Colorado who originally ruled on Trump's eligibility. He went out of his way to say that Trump engaged in insurrection, yet ruled that the Presidency wasn't covered by the 14th amendment, somehow. It makes no sense at all, unless you realize that judge probably realizes that if he ruled against Trump directly, he would have vigilante hit squads after him. So he made a ruling that at first glance favored Trump, but was guaranteed to be overturned on appeal, and since it's a higher court doing it, they have the budget for better security.
It has to be tough for these career politicians, who have worked their entire lives working their way up through the system, to get cock blocked by a guy who is likely senile and definitely dumb as a rock, but has their voters enthralled.
