Cruz admitted this. He said he didn’t cross Trump early because, in his words, “he didn’t want to get kneecapped.”
Well, a) that’s cowardly, and b) while it did leave him the last man standing against Trump, he still ends up where the rest of ‘em are, on the delegate ash heap.
And that was also an admission by Lyin' Ted that his supposed positive stance toward Trump for all those months was nothing but a ruse, dishonest and disingenuous in every way.
