I'm un-calling Romney/Santorum. This is only gonna be +1 to wingnut cred for his campaign (which is to say that he's not gonna be like Newt and trying to fund it by charging $50 for a picture with him), but he has no chance of getting the VP nod after this. No way in hell. He has overtly racist cooties all over him now and the non-GOPster public is going to shhhhy away from that (the US seems to prefer its racism to be unspoken these days, I suppose).
It's still gonna be Romney/wingnut though.
