Here's Jonathan Chait making the case for Obama:
It is noteworthy that four of the best decisions that Obama made during his presidency ran against the advice of much of his own administration. Numerous Democrats in Congress and the White House urged him to throw in the towel on health-care reform, but he was one of very few voices in his administration determined to see it through. Many of his own advisers, both economists steeped in free-market models and advisers anxious about a bailout-weary public, argued against his decision to extend credit to, and restructure, the auto industry. On Libya, Obama's staff presented him with options either to posture ineffectually or do nothing; he alone forced them to draw up an option that would prevent a massacre. And Obama overruled some cautious advisers and decided to kill Osama bin Laden.
I'd be voting for him if I had a vote, and those would be some of my reasons.
