Heh. They most likely haven't read any of his 15 books or are familiar with NVP's strategy to spout rah-rah, positive anecdotes that are hard to substantiate when you are put on the spot. In this role, DJT does have one ultimate goal: to persuade you to come around to his way of thinking and to see if he can out fox the "enemy" with secret information (valuable intelligence held closely to the vest) along the way. The urge to be right is strong in this one. Not a bad thing, and he usually is proven right. Also, I don't doubt for a second that he loves this country and its people.
While it's fun to think he's playing 4D Chess or is a time traveler (thanks to his cool Uncle's relationship with Nikola Tesla), most likely he's just winging it, which thankfully is based on a whole lot of experience. I've been a fan of his since "The Apprentice", where I found myself consistently agreeing with his rulings on who was working and who was slacking and who should ultimately be fired.
