The question becomes: will these educated Whites return to the Republican party after Trump loses, or does Hillary begin a demographic realignment?
If Trump is a sore loser and becomes the mouthpiece of the Republican party after his loss, I can see a lot of these voters fleeing the Republican party for good.
Trump is accelerating a trend that was already happening: non-college educated whites moving toward the Republicans while college educated whites moving toward the Democrats.
Romney won college graduates by 4% last election.
Romney was the dead cat bounce, though. The long term trend has been there since at least 1992.
Bush 2004 won college graduates by 16%, Bush 2000 won them by 11%, Dole lost them by just 2%, and Bush 1992 lost by them by just 3%.
Where is the long-term trend that has been there since at least 1992?
