No, He Wasn't.
But would you have blamed him - really - if he had been?
Um, wait. My wife reads this. I meant to say, I'm so glad that he actually wasn't checking out the ass of a woman clearly not his wife. That would be irresponsible and rude and just flat out wrong.
If you want to see a perfect example of how Drudge, Fox News and other right-wing ninnies are trying to make hay out of nothing, watch the whole video (it's short) and see how obvious it is that Obama wasn't looking at this woman. In fact, it's a pretty easy argument to make that he didn't even SEE her, let alone gape at her. (The same can clearly NOT be said for Nicolas Sarcozy.)
But let them spin, spin, spin. It's what they do best.
