This was from the 2004 election. Clearly the states with the lower IQ's went to Bush because of issues such as abortion, religion, guns and other Republican talking points. Naturally one would think that these low IQ states would be democratic since they earn less and need more help. However, for a very long time the Republicans have put the fear of god into these people and they have been voting the wrong way. What will be interesting is after this election what a chart like this will look like. I believe due to Obama's broad appeal that he will win many of the states that Bush won in 2004. Also note that he will be getting out the black vote in historic numbers this year - so he is bound to sway some of these states no matter what. I have very little doubt that 2 weeks before the election Obama has a clear lead and will likely win. It will be very interesting to see how much these results by state change. Note that I personally don't believe in IQ tests - I think they are biased. However I do believe in education and I would attribute this chart more to education than IQ.
