I would have loved a Perry/Santorum ticket. I think Santorum threw that possibility away last night. Imagine taking Texas and Pennsylvania. Some of these second tier candidates are not thinking ahead.
I came out of the gates hoping Santorum could get a VP slot, but I saw him pandering and protecting Romney in the last three debates, and he has continued to swipe at Perry while leaving Romney alone outside the debates as well. That has made me think he has his eyes on a Romney win and has chosen that route.
I have felt there were two different "alliances" building up these last few weeks:
1. Romney, Pawlenty (saw that even in Iowa), Bachman, and Santorum, and
2. Perry, Cain, Newt, and Palin will be there if she joins the group.
Those betting on Romney or getting deals from him with a positive outcome believed are making their moves to defeat Perry. Unfortunate, I think Santorum has decided to hold onto Romney's coat tails. We'll see if that works out for him.
