Just because it says Harvard on the piece of paper doesn't mean that the person who's holding that paper is smart.
My idiot uncle is a Harvard grad and he's dumber than a box of rocks with the attention span of a house fly. Einstein (as I sarcastically call him) warmed up a microwavable heat pack in a frying pan, and nearly burned the house down because he was reading something and forgot about the heat pack.
My father-in-law IS a rocket scientist, worked for NASA and other agencies with a top, top secret clearance and I have never met a man with less common sense.
He does vote Republican though.
