Trump is too dumb to come up with some of the stuff he says. Watch him carefully and listen. If he’s reading from a teleprompter, the words aren’t his. He always goes into a flat monotone drone voice when reading someone else’s words. He hates reading and preparing. The only thing he can write is his own flowery signature.
I have noticed this too. When he follows the script he definitely loses the passion. When he goes off the cuff he is exultant and enthused and totally off the rails making very little sense. “The man is not well” is the common theme here 74 days out. Brian Seltzer has a new book out “Hoax” that summarizes this argument.
