Trump is a disappointment to me, but then all presidents have been. His crime is rising to the top outside of the standard pathways. A person is supposed to start in lower offices, work their way up, and then jump from either governor or senator to president. Eisenhower was the allowable exception because he rose through the military, but he did rise through the system.
By the time anyone else is in a position to run there is so much dirt on them and dirt on their hands that they go along and get along. Doesn't matter which party, there isn't as much difference as people pretend.
Trumps position on the border is the same as that of Clinton. He failed to get rid of support for Ukraine. He's a 1990's New York City Democrat through and through. He's particularly scary because he now has in his tool kit the weapons prepared by the Democrats to bring him down. Every time, every damn time, I say "be careful the powers you give to your guy, the other guy will eventually wield them." I've been right every time I've said that.
You can call him Hitler or Nazi, or you can try to arrest this trend towards civil war. You can't have both. Which do you want? Do you want civil war? If you don't want it, what are you doing to defuse the current atmosphere?
