So what you're saying is that it's ok for Osama to make a glaring mental mistake like that but it's bad when McDouche does it? Makes no sense.
No. neither was a big deal.
But mccain looks worse, because he was lecturing obama on having a grasp on the region, then showed a big mental error. If obama had been dissing the crap out of mccain on stateside domestic knowledge and said 57, it'd be equally hilarious.
The fact that mccaain was chiding obama for being a dumbass (which in many aspect he is!), then making a dumbass glaring error, well, it's a little worse. You can admit that much, right?
