Trump made a crass comment about doubting Cruz’s conservative creds because his family came from Cuba.
Cruz, in what likely was meant as a tit-for-tat, made a crass comment about Trump having New York values, which was essentially implying the same doubts of his conservative creds.
Trump gets away with this, since these are the kinds of comments we expect from him, and because, hey - it’s Cuba, so say what you want.
Cruz doesn’t get away with it, because we expect better from him, and he unwisely (also unexpected from him) chose an American state as the subject of his taunt.
I think Cruz’s best move now is to just come out and admit it an ill-advised turn of a phrase in an attempt to get even with Trump over his Cuba comment, and apologize to New Yorkers.
