I think some of it has to do with the Texas accent and people just assume that means he’s ‘dumb’. That’s a type of bigotry in itsef - just because he has the same accent as George Bush doesn’t mean he’s the same person. There are a lot of people in Texas, it’s just a stereotype.
See post 12 for why Perry is dumb. Trust me, it has nothing to do with his accent or where he’s from, it has everything to do with his inability to form simple sentences.
Are we to hold it against Cain that he has an accent like Jimmy Carter?
