Donald has typically created the desperate circumstances he's always inhabited in his head. Little Donny is so threatened. He's so fragile. He's so afraid. Afraid of what?
He must fight and conquer. Conquer what? He was born independently rich. He thinks he's vulnerable. He thinks he's up against the wall. In other words, he's delusional.
But he unwittingly makes his delusions real. Notice how comfortable he is fighting for his political life now. And how he seemed to relish his "victory" over the virus.
Don-Boy is totally nuts.
