Last week, McCain couldn’t remember how many homes he owns. Now, Think Progress points to a 2007 interview when he not only didn’t know how many homes he owns (in the interview, he was only willing to admit to two homes, when the real answer is at least seven), but amazingly he didn’t know what kind of car he drives. Instead, he had to ask a nearby aide, who replied “A Cadillac CTS”.

Who doesn’t know what kind of car he drives? Does he even drive anymore? How old do you have to be before they take away your license?

And what kind of person drives a Cadillac CTS, anyway?
