I think he is good at marketing and self promotion and getting people worked up, but I don't think it's calculated (at least not by him). I don't even think that part is all him as I am sure most of the online stuff is written by somebody else. A lot of it is intentional, but if he gets challenged on things on the spot like in a debate or press conference, he often melts down and I don't think that is intentional. When put in a situation where being somewhat intelligent might be to his benefit, he fails. It's frustrating to me that all the influential people in the country keep letting hm get away with it, becase he is easily exposed. Harris, who is no rocket scientist, totally manipulated him in the debate.
