More Variation in State IQ Scores = A More Democratic State

The wider a state’s intelligence distribution is, the bluer that state tends to be. In addition to inequalities in educational attainment and wealth, inequalities in IQ are also good for the Democratic party. So the party putatively determined to reduce inequality benefits from doing just the opposite, while the party putatively more tolerant of cutthroat competition and the winners and losers it produces benefits not from economic wins and losses but from draws. — The Audacious Epigone

So, the data show us this, but data don’t say why. What is your explanation for why this is the case?
