I've seen several articles over the course of the presidential campaign referring to "Donald Trump's movement." Unless they're referring to his bowels and the crap he spews verbally every day, they couldn't be more wrong.
There is no movement. If there were a movement, we'd see others following his path into office, but Trump is only about Trump. What they call a movement is nothing more than the demagoguery, exploitation, and ego of a man who desperately needs attention and validation.
He is an extension of the coarsening of public dialogue, in the footsteps of loudmouth political talk radio and TV hosts. Rather than the leader of a movement, think of him as the country's most famous internet troll.
