On Obama as an ENTP: He is absolutely an ENTP. It's almost clear as day to me, and I've been following his career closely for now nearly five years.
On his Presidency: He has done all right. By Bush year standards he's Jesus Christ, but I don't set the bar for the office that low. He has his good points and bad points. On the positive side, his overall views are about as much as I could hope for from a major US politician. (Energy reform, healthcare reform, no torture, supports civil unions, wants to end dont ask dont tell, doesnt support abstinence only education, ended federal raids on medical marijuana patients, etc.) On the negative side, everyone knew he was inexperienced, and that is showing. The entire handling of this healthcare debate may not be Carter-bad, but he's hardly showing a Lyndon Johnson-esque ability to get things done either.
On foreign policy: Very solid work. He is quickly helping to repair a world image that was trampled upon for the last 8 years by the previous administration. The entire educated world knows that it's wrong to torture. Not apologizing for such despicable acts isn't seen as "tough", it's seen as petulant, childish, stubborn and bullying. Apologizing shows maturity, depth of character, humility, and remorse. The terrorists aren't afraid of our words. They're afraid of our unmanned drones. The Obama/Clinton foreign policy team gets an A thus far from me.
