From Paul Waldman, after noting Rick Perry's aggressively maintained more-Texas-than-thou persona:
It's true that voters in the Northeast, Midwest, and West may have an irrational, kneejerk reaction against his voice or even just his home state, without actually knowing whether that reaction is justified. But the truth is, in his case, it pretty much is.
For the record, I don't think Perry can win the Republican nomination, and I know that he can't beat Obama in a general election. I'd love to see him try, though.
