I don't believe he is stupid. Far from it. I'll give you this .....he may act stupid...and he is challenged. Now especially with his new job. But it is a challenge he is taking head on and will continue to do so I believe to the best of his ability. Not that it will wholly work. I will   be HAPPY if he succeeds in 50% of his " promises". I don't believe he is stupid.  Far from it. He IS  mentally challenged   ( in addition to  job  challenged ) . 4%  of  people are psychopaths.   ( some  x presidents), many more than that are narcissistic.  Many more than those two combined are depressed, many severely. I can go on and on. We all are in some ways mentally challenged  and certainly Trump is. So what. Predjudiced? He is president . Period. It's your right to dislike or even hate and rage at him . See where that gets you. Unfortunately I say and concede to this. Given his not to uncommon mentalities .... given enough rope I see him hanging himself.  I in all earnest HOPE not.
