Meh.
I already have lots of reasons to dislike Romney. Hammering Perry on illegals is one of the very few things he has done that makes me have any hope for the RINO.
And it has made absolutely no change in my opinion of him. He will say ANYTHING to get elected. I don't believe him on this anymore than I believe him on abortion.
SHOW ME. You can tell me whatever you want, Mr. Romney. Until you have any actions whatsoever to back your stated positions up (and to counterbalance the fact that your actions in the past are opposed to your current positions) you will never get my vote.
Oh, and telling your contractor "We can't have illegals here, for Pete's sake, I'm running for office!" REALLY doesn't go over very well for the sincerity of your position.
