The American Assembler offers a chart that appears to indicate that states with higher average IQs voted Democrat in the 2000 presidential election.
Addendum: I initially posted this in the comments but realized it would be better to include here. I re-checked the site, which now offers a correction:
Error Correction: The source of this data is not "Wealth of Nations" as it had been attributed to us. A reader writes in and tells us he has the book (Sorry to hear that Mike) and the state IQ's aren't in it. This is a huge relief as the book is one of those race/IQ books. So we're still trying to track down the source for the IQ scores. As this is all a bit of good fun we aren't to [sic] concerned with the source.
So take it with a grain of salt, as I should have in the first place. I'd prefer that they care about having a reliable source, even if it is just for fun.
