>> but I don’t find myself trusting him (Rubio) on policy—especially not on immigration policy.<<
I realize Rubio has screwed the pooch with many people by signing on with the Gang of Eight, but I honestly think he learned from that experience.
I don’t know which debate it was, one of the earliest ones though, but in it he gave a very good explanation as to what now has to be done and that he had learned that it couldn’t be done the way he’d set out initially to do. In short, he sounded like he’d sincerely learned his lesson and that he was now setting out on a completely different course to address the problem, one that, if followed, I suspect most of us would probably sign onto.
I don’t recall the details, however, and obviously it’s a make or break issue for a lot of people. However, not as make or break as one would think, since Trump is every bit as much for some form of amnesty as any other GOP candidate, and more so than some of them, yet the hardest of the hardcore “no amnesty” group seem to be fine with Trump.
Maybe it's not that simple. But if many of Rubio's generally conservative backers want to call it water under the bridge, it still smells a bit too much like sewage--and we all live downstream of this political bridge.
I prefer Cruz because he told the people of Texas what he was going to do--which was essentially to oppose the Establishment Republicans--and he went ahead and did it. IOW, I am proud of him for not getting along very well with most of his fellow Senators.
