50% of Santorum turns this into a blowout for Romney. Newt needs to do better than that. I have a sneaking suspicion a large number of those supporters will sit it out now rather than vote for either of the candidates who trashed the one they were supporting. Perhaps if Santorum endorses Romney, some might get angry enough. Hopefully, Santorum will either not endorse or will support Gingrich.
Still voting for Newt over Romney!
From what I've been told Santorum will endorse Romney, and boy do I hope that is wrong... My point was if Newt is gaining NEW support and, along with that, picks up 50% of Santorum, that would great... much better than where he is now...
Santorum is a politician. He will do whatever he feels is best for his future career as a talking head/2016 candidate.
