Phil notes that Bush gained support among higher-income voters; Ruy Teixiera has pointed out the same thing. But Bush also gained among the non-college-educated, but not the college-educated. How can this be? After all, college-educated voters earn more money. How do we solve this paradox?
Maybe we're really looking at an age effect -- many younger voters (who clearly trended to Kerry) are well-educated but lower-income. Bush ran strongly with older voters, many of whom are experiencing their lifetime peak incomes even if they are not as well educated as their younger counterparts.
