My thoughts on this:
I agree with what Ted Cruz said. We all agree that Obama is lawless and that is impreachable and that it is the House that would do that. We all know that the Senate is never going to go along with it.
I used to think impeachment was a "big" thing, Nixon resigned rather than go through it. But after Clinton was impeached and then still went on "presidenting", I think of it as a meaningless gesture - style over substance. There are plenty of reasons to impeach Obama, but it would be a distraction and what would it accomplish if he just stays in office and he and no one else has to pay REAL penalties for breaking the law? Impeachment is too good for Obama!
Sarah Palin is correct when she says Obama is a candidate for impeachment - and her base likes to hear her be tough and direct like that. She can say it and it won't "hurt" her. Ted Cruz realized that when he stuck his neck out and was tough and direct, that his party didn't have his back, in fact, they were aiming at it. Add to that, he saw that the media was doing a Palinization of him - turning him into a joke - further enabled by the GOPe (which was terrified by Cruz). I'm sure he does have larger political aspirations, and like Rand Paul, has astutely recalculated his political approach to get to the place he wants to be. I don't think that is a bad thing if you are still keeping your eyes on target and not compromising your principles to do it. But again, I agree with what Cruz said, so I don't think he has compromised his integrity - he is being smart.
