Not ignorant.
What it really is, IMO, is everyone has gotten smarter about disguising their beliefs and hatred. It's slick, and if you pull back the curtain, they yell that you are oppressing them as they try and push their oppressive agenda.
But that's all a red herring. It doesn't matter what stupid reason, bigotry, hatred, ignorance Trumpallos have for voting for him. It only matters that they are. Because 'anyone but Hillary' doesn't (or shouldn't) apply here.
Someone created a test, and created the worst political candidate this country has ever seen. Maybe it was a joke, a bunch of MIT pranksters. Wouldn't surprise me. Whole bunch of people are failing the test.
What's it take? What does it take for Trump to lose these people's votes? He's an internet troll, a FFA alias come to life. And millions of people want him to run the most powerul country in the world.
