This is nonsense. Trump is a populous president. Like him or hate him that is his thing. His thing is turning the will of his base into reality.
Clinton has evolved on some minor issues, but her thing is being establishment which brings with it some internalized power. She does not have to agree with the public, she does not have to do what they want. Do you think the public actually wanted a war with Russia? No, that was just the politicians.
If Trump had been a politician for any amount of time we would of seen that as well, his base simply has not changed any of their opinions. Their were multiple times throughout the run where he tried changing his message and went back because of the feedback. That was actually one of the most common insults used on him throughout the early and middle of the race, that his policies changed every time you spoke to him.
