The ruling class narrative has been an inevitable Romney. The result of that has been a few good candidates falling by the wayside playing the not-Romney game. If we get someone besides Romney, I don't think any of the three remaining are the best that were running. Any one of the candidates who were banking on early wins could have stuck it out and found themselves in the position of the alternative to Romney. If they had, it could have been Santorum who bowed out early.
That said, I'll be happy if Santorum wins, or even forces the establishment into conniptions along the way to a close loss. He's every bit a decent guy as Romney is, and he's at least been who he is for a couple decades.
