I agree with your tagline, but sure about Santorum’s motivations. We may only be certain if Romney ygets elected and Santorum gets appointed to some cabinet post.
But right now, he looks like a conservative, as is Perry and Gingrich and we are running out of alternatives here.
I think both Perry is doing the Fred Thompson Fan Dance in order to give us another RINO nominee. I’m not sure about Gingrich but he represents the same caste.
