These people presumably thought they were voting in their self-interest when they chose Trump. This leads to the question, "what do they consider their self-interest to be?" They see themselves losing important social and economic federal support, yet they would vote for Trump again. I don't think those Trump voters are either reflective concerning their true interests, or very self-aware. If Trump has any genius, it is in identifying and manipulating the most irrational and even brutal instincts of a large minority of Americans.
