I think Trump has been a closet conservative in a liberal town for a long time. His conservatism may be eclectic and not well polished, but I think he listens to experts in the respective fields.
I agree. He seems to be driven to achieve deeds rather than order and comprehend theory. He is not an ideologue, but he is more of a thinker than he is portrayed or chooses to project. He is “misunderestimated”, and likes it that way IMO.
