I have to wonder about the statistical accuracy of that info though. The chances of getting a good sampling of people from all across the spectrum, in terms of education, age, etc, is very slim.
Although education level does not necessarily correspond positively to IQ (there are some pretty stupid people with college degrees these days), most IQ tests are geared towards people with college degrees. These peeps are used to taking that kind of tests, and since the percentage of college grads in the blue states tends to be higher, the IQ scores will also tend to be higher. Most of those snooty, uppity blue-state types will do better on those kinds of tests, but that doesn't mean they're necessarily smarter. I'd like to see them try to do something useful, like fix an engine, or install a new water heater.
