This is a man who has demonstrated an extraordinary and heretofore unrivaled degree of ignorance and stupidity on the public stage. Clinton's no angel herself, but at least she has a brain. I think there's an IQ hurdle a potential candidate needs to clear and even though it's relatively low, Trump has managed the astonishing feat of not being able to meet it. That alone disqualifies him. Any further arguments are irrelevant.

That's why one feels compelled to assume that Trump supporters - the ones we would otherwise assume are reasonably intelligent at least - must have an ulterior rationale for their vote. The most obvious explanation is closet bigotry.
