Jeraldine Ferraro's remarks are amazing! In truth, within the Red or Kerry states (colored blue by the media), the counties with the best education mostly for Bush. At least that is true in NJ.
Educational level correlates roughly with Republican voting. Among the best educated people in the country are Mormons (I am not one), and their states are heavily Republican (check Idaho and Utah!).
Actually, to be very blunt, there is not a very strong correlation between intelligence and anything political. It seems that tradition and a sense of loyalty (for example, to family and country and religion) are more important.
Ferraro is just getting beset by hatred, and is starting to hallucinate. That happens when the blood temperature in the brain gets to high.
I think there is demographic information and statistics that might suggest otherwise, but I don't wanna touch it..
