I saw an article on Red State (by Erickson) slamming Santorum for his sins against conservative principles - for medicare part d, against NAFTA, voting for the minimum wage, etc.
The obvious question becomes: what do republicans want? Erickson is clearly against Romney, yet he has trashed every anti-Romney. Now he's arguing Santorum has no money and therefore a media led surge for him will only hurt the candidates that have a shot at beating Romney - Perry, Bachman, and Gingrich. You know, the three candidates he and other conservatives trashed at one point.
Romney will probably cruise to the nomination, outside of losing South Carolina. Not that him winning was ever in doubt, but conservatives could have held him off if they consolidated behind one candidate. Right now Bachman, Perry, and Santorum all have around 10% in Iowa - together that's 30% that's against Romney; hell include Gingrich's support and you're at like 43%.
