Judging from the family that I still have there, this video is absolutely accurate. My most liberal relative (claims to be an independent) hates Obama but cannot articulate exactly why (she also refuses to use the n word in public, so draw your own correlation). The rest of them unabashedly refer to me as a Yankee (I'm from the midwest) and the ex-husband of one of them actually told me (when I was about 15) that if I kept bringing my liberal views down there, he was going to change my mind...while he was playing with a rope...
Far as I am concerned, a catastrophe that wiped out the majority of that state's residents would raise the average IQ by quite a bit.
