That was true in the 2010 elections. Republicans swept. They beat out Democrats in lots of categories Democrats usually win. But it isn't true currently, and it wasn't true in 2008. Obama won people with college degrees by a substantial margin in 2008 and over the last couple years we've seen a major swing with uneducated white Democrats going Republican and educated white Republicans going over to the Democrats. All the anti-education, anti-science, simplistic slogan stuff comes with a cost. They're trying to take uneducated white voters from the Democrats, and they're succeeding, but the cost is losing educated white Republicans to the Democrats.
