I realize you were not disparaging rednecks. And I had not heard of the "Redneck Manifesto," but just a read a review. It sounds like the author hits a lot of good points. This one especially that was mentioned in the review, "he shows how 'white cash' has always pitted 'white trash' against blacks with a divide-and-conquer ploy." You know, a lot of folks in redneck land liked Bill. The economy was good, most importantly, and they thought it was cool he had sex in the Oval Office (those rednecks who are not practicing Christians, and a lot aren't). But I agree that I don't think they will go for Hillary. There could be some sexism involved here, but they're not all that way. They won't go for Kerry either.
For the record, I'm not a redneck though I'm in a redneck profession. Went to private school, country clubs, and grew up in the city. So most of them don't like me either. But I guess they're part of that swing-vote for either the Rep.'s or Dem's.
