I don't know. I would think it's a little worse that an American raised in America who's running for the Presidency doesn't know how many states are in the very country he's trying to lead. 
That being said, they both suck.
agree they both suck.
but... obama was doing the math in his head, counting the 3 states he hasn't visited, and then said 57, instead of 47. If anyone had to bet their life savings if obama thinks there are 50 states or 60 (3 less than however many he visited) I think we'd all admit he probably doesn't believe there are
60 states.
Mccain's mistake isn't a big deal... but it is a little troubling in light of all the other verbal miscues he's had about the area in which he claims to bs the strongest, the military and natl defense.
