A Theory about the Trump Movement
I suspect the basis of the Trump movement is the belief that success should only be based on prowess instead of diligence. All else is commentary. The Trumpkins resent foreign competition and immigration because they think of it as based on the unfair use of diligence by foreigners. They don't trust the Establishment because they think of it as a fraudulent establishment by diligent people who have usurped the role of people of prowess. They especially dislike Ted Cruz for his use of diligence and lack of prowess.
