Obama can't leave, no matter how much sense it makes. He would be branded a quitter and loser by Rush and the 2012 candidate.
Bush didn't leave afghanistan and didn't prosecute the 911 terrorists - he should have done both. I'm sure we'll see more and more bags of shit Obama inherited from the last Prez that he'll be criticized for handling.
of course, he'll return the favor to President Huntsman in 2013 with the healthcare thing...
