I think Ben Carson was the first wake up call for me. As a grad-school dropout, I couldn't believe this loon was a doctor, or look at ACB on SCOTUS for example, or to the full absurdity; Rudy G. Maybe it's the university they attended, maybe it's an exceptional ability to compartmentalize, but I never knew before the past five years or so how many well-educated professional people are total loons.
And although I have admittedly known several well-educated looney liberals as well, especially living in Ann Arbor, it's a different kind of lunacy. It's the difference between legislation narrowing down a busy thoroughfare to make another bike lane vs. actively encouraging the spread of a plague that has killed about as many if not more people than Germans did during the Holocaust.
Apples and oranges I say.
