And it hardly needs to be pointed out...
Educational attainment of Democrats is higher than Republicans:
Democrats now hold a 12-point lead (52% to 40%) in leaned party identification among those with at least a college degree, up from just a four point gap seen as recently as 2010 (48% to 44%). Much of this advantage has come among adults with post-graduate experience; currently, 56% lean Democratic while just 36% lean Republican. Among those who have received a college degree but have no post-graduate experience, the gap is much narrower: 48% identify as Democrats or lean Democratic, while 43% affiliate with the GOP or lean Republican.

There is a reason republicans slash education funding and slander teacher unions. There is a reason they attack science and view scientists as the enemy... its a matter of survival for them... an educated populace will not elect them, so its best to keep them dumb and suspicious of the educated...
