Santorum is still in trouble, but I think his TV ads are excellent, and he is back in the hunt. Yes, I think odds are, Santorum will likely lose, but he has maybe a 1 in 3 chance of winning now, and that is a lot better than where he was a month ago.
If Santorum can ever get Casey to debate him in Pennsylvania, Santorum's odds will go up dramatically. I thnik Santorum will pull it out.
