My wife and I were having dinner with another couple a few weekends ago, and the topic of the election came up. We told them we were 'Anybody but Bush' people, and they admitted, kind of sheepishly, that they had voted for Bush. He described his decision making process: 'I watched the debates, and made a decision based on that'. At this point my wife and I had to be careful to not make eye contact for a bit for fear we'd start laughing.
Plenty of fairly intelligent people voted for Bush, sure. Using the TV debates as a justification, though, is kind of like saying 'Oh yeah, I bought the Milli Vanilli album back in the early 90's, but I did it because the lyrics really spoke to me'.
