Pundit Nation already has the You Tube video political leftists will cling to - McCain did not shake Obama's hand, but had his wife greet him instead.
Look, if McCain really wanted to be a snot, he would have steered his wife away from Obama, not towards him.
Of course, I would have to steer my wife away from Obama before she asked him if that's the hand he used to shake Bill Ayers' hand. Or if that's the hand he wants to use to shake the hand of Iranian dictator Mahmoud Ahmadinejad. Or if that's the hand he refused to share with wounded American soldiers while he was shopping in Berlin.
My wife is rather fussy about whose hand she shakes.
