Nobody is going to vote for that phony Romney.
Romney/Cruz? Two never Trump peas in a pod. Do sore loser laws apply to VP slot also?
Yes, he could not run in anywhere on a presidential ticket in Texas. To be fair, 'sore loser' laws have been stricken or bypassed in all but two states. But Texas being Texas, you know they mean it, and they would defend the law (or tie up the challenge past the election) - even from a 3rd party run by a 'home son'.
