I totally agree that trump is weak and all of the other things you said but, because he is a narcissist, he cannot admit that to himself. He cannot admit that he's a conman or a grifter or a lowlife or a liar or a total fucking scumbag. To do so would cause him irreparable psychological injury. That's why we see him right now kind of decompensating. He is experiencing narcissistic injury which he is seeing as Judge Marchan is not letting him go to the Supreme Court next week, or letting him go to Barron's graduation (like he even cares about that I'm guessing). It's not because he really wants to go to those things, it's because he's been the one who is on top and makes the rules. He's the one who bullies everyone into doing what he wants them to do. People don't usually tell Don what he can and cannot do. That just messes up his vision of his power; the vision he has because he's such a broken man, that's the only way he can see the word. He is the world and the world is him. He is the only thing that matters in the world and everybody really needs to get with the program and see that. And yes, he bullies other people because really, he hates himself, but again, he'd never admit that even to himself.

The world saw how he cowered before Putin and acted like Putin's Reek (isn't that what that character on GofT was called?). Only trump didn't see himself as cowering. He saw himself as being an equal and that Putin liked him and they were great pals. His world view is terribly skewed. He probably grew up with people letting him think he was the best at everything, the greatest, all those superlatives that he uses now. 

I always said that if I was around that awful person and was talking and he said to me, like he does, "Excuse me, Excuse me" when he wants you to stop talking so he can talk, that I would tell him "no, I'm talking right now" like who the fuck do you think you are? But he also has nothing to hold over my head. (Just don't tell him that my son works as an analyst in the Department of Homeland Security with the Countering Weapons of Mass Destruction Department or else he might not have a job any more. Of course, I've told my son that I don't care what kind of security clearance he has or how specialized his job is, if trump wins in November, he'll be without a job so he better suck it up and vote for Biden instead of his usual Libertarian candidate.)
