Trump wasn't voted in for his competence or statesmanship, because he obviously lacks any credible political experience. He was voted in on the basis of his incompetence and political incorrectness by people who wanted to see the system burned to the ground, and the mainstream ridiculed.

I can't imagine there is anything Trump could do to upset his base other than be good at his job. Given the number of blunders and gaffes he's already accomplished before even being sworn in, they must be thrilled to be getting what they wanted.
