How Dumb is Mitt Romney?

I have thought for some time that while Mitt Romney seems to be good a rubbing money together to make more money he's really not very smart.  If this doesn't prove my point nothing does.

Romney Doesn’t Understand Why You Can’t Roll Down Windows On A Plane

“I appreciate the fact that she is on the ground, safe and sound. And I don’t think she knows just how worried some of us were,” Romney said. “When you have a fire in an aircraft, there’s no place to go, exactly, there’s no — and you can’t find any oxygen from outside the aircraft to get in the aircraft, because the windows don’t open. I don’t know why they don’t do that. It’s a real problem. So it’s very dangerous. And she was choking and rubbing her eyes. Fortunately, there was enough oxygen for the pilot and copilot to make a safe landing in Denver. But she’s safe and sound.”

Well there is a very good reason why the windows don't open - if you did open one and you didn't get sucked out you would die from depressurization. And this guy, who is dumb as a stick, want's to be Commander in Chief.
