Oh, I am very comfortable with the diagnosis of Narcissistic Personality Disorder for him. It is very, very rare, but he meets the criteria perfectly.
I actually was unmoved and truly had no emotional reaction when he said that he wouldn't accept the presidential results. I didn't believe him when he said he would. He can't. He simply can't. How much noise he will make I have no idea. But, he has to make SOME. His "illness' (forgive me for the term), won't allow it.
He sees himself as unpredictable, but I find him very predictable.
The other stuff is just your usual run of the mill racist, sexist, etc. person.
ETA: I also love watching Donny Jr., try to make the same head shakes as his Dad when listening. He always tries to replicate his way of speaking. Cracks me up. Sad too...he is just so desperate for Dad's love.
