1.) I believe Donald Trump is playing the part of president as his final act in show business. He won the part of favorite son of the fundamental Americano-christian base out of 17 candidates and now has a contract for 4 seasons in office and a weekly script written by professional social-engineers to keep the show interesting. When all is said and done, he will leave the office having allowed the current show's operators to move some dials and levers in their favor and he will be either discarded quietly, killed off heroically, or reduced comically into insignificance like many other show's antagonists.
2.) While I have long harbored an extreme displeasure for the man he pretends to be on tv, and even more so lately for his and his swampy ilk's plan for my country, he is undeniably "smart". For years, he has taken part in a system that preys upon the stupid and naive and relieves them of their hope and money. It has required the skills to manage emotions and the emotions of others at a higher level than what most people are capable of. He is manipulative and has shown a capability for planning large organizations or executing complex plans successfully so in one way or another, I believe he may be a smart person. I will gladly suggest without any medical training, however, that his clear malignant narcissism has become too overwhelming for him to control, leading to a severe impeding of his decision making possibly multiplied by some other kind of neurological disorder which brings us to three.
