Many of Donald Trump supporters like him for a variety of reasons. Some of them like the idea of banning Muslim immigration (which he's already stopped supporting). Some of them like the idea of building a wall (despite opening the door for amnesty). But a lot of them were against the Republican Establishment........except Donald Trump is the candidate of the Republican Establishment, has been for a while, and they've been propping him up all week in Cleveland.

If you supported Trump because he was against the GOP Establishment, you've been had.
