What we see so far in Trump is a reflection of intense anger by a subset of a subset.
As to Ted Cruz, he has never put a foot down wrong, I know of no single gaffe that the man has ever committed and I would welcome you posting such an example. The idea that Cruz will be tripped up by the media has no foundation in history.
Moreover, Cruz will not offend the mushy middle as Trump does every time he exhales.
Cruz voted for TPA, a green light for Obama, and loves dumb trade as proven by his editorials.
He only reversed himself because he saw the political tea leaves. Too late. TPA makes it impossible to block TPP.
