How about Cruz wanting to bring the illegals out of the shadows?
Cruz was afraid a bad bill was going to pass and proposed any amendments he could to try and make it better. So that amendment was to remove the chance for any illegals staying to get citizenship. It didn’t mean that he wouldn’t block any amnesty if he thought it would’ve passed. And he was never going to vote for the Gang of 8 bill no matter how many improvements he got amended to it.
