The movement is dissatisfaction with the Republican party establishment. Trump is just the face of it. It isn’t dependent on Trump and would be present even if he hadn’t run.
I was at his Rally in Raleigh NC this past Friday and I can tell you it is a movement! People were coming into the over crowded rally even as it was ending. 7 groups or individuals were booed out especially the BLM crowds and the illegals supporters.
It’s a revolution.
