Of course you don't understand. You literally just stated Hilary voters were uneducated, when reality shows that more educated voters skew Democratic. College can't fix the willfully ignorant, and it doesn't work for everyone, there is no 100% solution.
But, if you do get a higher education, and then actually apply yourself a bit and learn, you will be exposed to more view points, history, the experiences of others, the power of critical thinking - all things that drive people to the modern Democratic party.
Republicans appeal to more primitive and base populist emotions like nationalism, fear, anger, the other - quite similar to those things that led to the rise of fascism in the 1930's. As a Facebook executive casually mentions here:
