That link is bullshit, it has been proven to be an internet Hoax. It is the same one that was put up before when Gore/Bush ran 4 years ago. Some magazines have published it thinking it was factual data but then issued retractions. Here is one from the
Economist
Retraction from The Economist
"Clueless in St James's .......Last week we published a list that purported to show the IQ s of states voting for George Bush and Al Gore in 2000. Alas, we were the victim of a hoax: no such data exists. By way of apology, here are two very crude ratings of states' intelligence-and how they voted. (Two charts shown for states (1)Math scores for 14/15yo (2) %holding a Bachelor's /gree or above) "
Here are a couple links that show what is really going on.
