I agree one part of what you said - It's great that he repealed Don't Ask Don't Tell, and even better that he's openly "changed his mind" on the issue of gay marriage.

Now here's my "negatives" list -

1) You say that Obama "ended the war in Iraq." Well, he actually followed President Bush's timetable.

From the 2008 Status of Forces Agreement, "All the United States Forces shall withdraw from all Iraqi territory no later than December 31, 2011."

To top it all off, while the U.S. troops have left from Iraq, we left behind thousands of private military contractors with automatic weapons and armed helicopters. And that's just the stuff they're willing to tell us about. And for those who say, "Well, they aren't going to be fighting anybody, they're just bodyguards for diplomats," - in Afghanistan in 2011, contractor deaths exceeded those of American troops.

2) While Obama was "ending" the Iraq war, he was also pretty busy conducting covert one in Yemen. These drone attacks are have killed at least 500 people in Yemen, up to 8% of those being innocent victims. "Of these deaths, 99% occurred during Obama's presidency."

Jeremy Scahill, who reported for NPR on Yemeni affairs, has done two scathing reports (1, 2) on Obama's actions in Yemen. In his NPR spot which I can't find right now, he shows that the reality is much worse - we are giving the Yemeni government money in return for allowing us to do these drone strikes. They are using this money to fund a personal army for the anti-democracy government. What's more, they are gaming the system by allowing terrorists to operate within their country because it justifies the U.S. paying them to do drone strikes.

3) Obama's justification for our involvement in Libya. We took a nearly secular country and we created a situation where Sharia law is a "Fundamental source" of legislation.. I love this quote -

"Does anyone honestly think jihadists fought to overthrow Gaddafi to replace it with a secular state? This isn't to say that jihadists won't accept our help. They're perfectly fine if NATO air power can help bring about an Islamic fundamentalist state in Libya. Just don't expect them to show any gratitude for it."

4) Further driving up the U.S. debt by $5,000,000,000,000 (yes that's five trillion dollars). Certainly a portion of that rolls over from Bush, but I don't think people realize how much of a problem this is. Sure, we are now able to get extremely low-interest loans from the capital market because of the idea that the U.S. will never default on its obligations. But this will not last. We were in the same position Greece is currently in, except we had the luxury of ballooning our balance sheets instead of being forced to adopt austerity. When the balance of power changes internationally, and the U.S. does not have the purchasing power it used to, what is to stop China from devaluing the dollar by flooding the market with billions is has stockpiled? We don't have the money to pay our debts. Do you have $45,000 sitting around? 'Cause that's how much you owe thanks to our government.

5) Increasing raids on medical marijuana after stating explicitly he would not do so as has been discussed ad nauseum here.

6) The fact that we are gearing up, no matter who wins the election, for more conflict in Syria, Iran, and anywhere else we can position ourselves to keep the U.S. dollar important internationally.

7) By the way, I wouldn't mind seeing some federal legislation that would make it illegal for States to deny marriage based on sexual orientation.
