Steve Kornacki compares GOP primary voters to the general electorate:

Ironically, immigration and the HPV vaccine are probably two of Perry's best selling points as a prospective general election candidate. In the fall of 2012, he wouldn't need to apologize to swing voters (as he did to Republican primary voters Monday night) for trying to reduce the incidence of cervical cancer, or for believing that every child who graduates from high school ought to have a fair chance at going to college. These positions would help him combat Democratic efforts to paint him as an extremist ideologue. But within the Republican Party, he's vulnerable on them.
