Wars - Disapprove. He did the right thing in Iraq, but at least as far as my judgment is concerned, he's a victim of his own success on that front. Afghanistan is now more important than Iraq, and I don't approve of the way he's conducted himself on that front. He needs to either **** or get off the pot...not do a half-assed surge at the same time he announced a future withdrawal. Meanwhile, Pakistan appears to be coming apart at the seams, and the US military does not appear to have any well-developed contingency plan to deal with the total collapse of an allied nuclear state.
Economy - Approve. For the most part, he's made the right moves. He bailed out the banks, provided a much needed economic stimulus, extended and improved unemployment benefits, reappointed Bernanke to chair the Fed, and will soon pass financial reform. He's made a few mistakes too - the handling of AIG and the bailouts of the auto companies - but he's had far more successes than failures on this front.
Foreign policy - Neutral. I assume this category encompasses everything except the wars? I didn't vote because I'm torn. I do think that his outreach to the Islamic world is extremely important and unfortunately he isn't getting the credit that he deserves on this front. Obama also deserves credit for (what I think) will become more apparent in the next couple years: He's managed to coopt Russia into playing a constructive role in global affairs, rather than be a gadfly. But at the same time, Obama has needlessly irritated some of our allies for no discernible reason on repeated occasions. Specifically the UK.
Tax policies - Approve. I'm glad he didn't try to raise taxes during the recession, but I'm also glad that he recognizes that we'll need to roll back the Bush tax cuts in the long term in order to generate revenue.
Bureaucracy - Approve. With the exception of Eric Holder, I like everyone he's appointed to his cabinet and high-ranking staff.
