we only left Iraq because the new government got tired of our shit
Obama promised to end the war. Despite the right wanting us to remain and Mitt Romney campaigning on a platform of extending the Middle East conflicts for years, Obama had all troops out in less than 3 years and plans on having tens of thousands out of Afghanistan this year. Again, he's doing the best he can with the Republicans trying to block as much as they can.
and bomb Libya to "help the resistance" (good thing that logic carries to Syria)
Wrong. As in, factually wrong. NATO, as well as Jordan, Sweden, and the United Arab Emirates, all participated in enforcing a no-fly zone and protecting civilians, voted on by the United Nations Security Council. The only bombings that occurred were of government targets that had been involved in the deaths of neutral civilians. Had NATO actually planned on helping the resistance, it would have been over much faster. Not to mention that the French provided 35% of all air strikes committed during the intervention. Had the rebels begun striking civilian targets, they likely would have been shot at by our drones too.
The reason we're not intervening in Syria is because the United Nations hasn't voted on doing so. There has never been a specific effort to help any resistance movement in the Arab Spring, only a single 7 month enforcement of the UN policy that indirectly assisted the rebels and ended almost immediately after the civil war ended.
and now everyone is legally required to purchase health care.
As is done in a large number of prosperous first world countries, where they
don't complain about having guaranteed healthcare instead of having to privately pay for very expensive health insurance (regardless of whether it gets used). I have yet to see anyone negatively affected by the reforms, regardless of their whining. Because that's what it is: whining.
Obama didn't even come out in support of gay equality until Biden gaffed and the polls were in his favor.
Contrary to popular belief, Obama coming out in support of gay marriage before the election would NOT have helped as much as you think. The people who were already inclined to vote for him would likely support it, while those who would vote for Romney would likely be against it (or at least want him to abstain from civil rights in favor of something else first). The only people his decision would have affected were the voters on the fence, which could have hurt him as much as it helped.
The guy's more interested in looking bipartisan than he is in keeping his promises or upholding the agenda that got him elected. If he really believed the things he said, one would think he'd put more effort into defending them; it's not like the Repubs have made hard targets for mockery and ridicule.
It's a matter of trying not to alienate people. Obama's election massively divided people, and anyone can tell you how many death threats he's received since coming into office. Mitch McConnell outright stated at the beginning of Obama's presidency that he wanted to make Obama a "one-term president", echoing Rush Limbaugh's desires the previous month that Obama would fail. The GOP has been more concerned with making Obama look bad to historians and preventing him from doing what he wants than actually working toward bettering the nation. Very few people in this day and age (now that we've left the Tammany Hall standards of politicking) have the clout to get people on both sides to play nice with each other; just look at the health care debate.
Again, the idea that Obama could accomplish everything and be Jesus in a suit if he just played hardball is a fallacy and a bad misunderstanding of the power of the presidency, and the history of presidents. Only
75 percent of campaign promises made from Wilson to Carter were actually met. According to the
Obameter, in fact, Obama has kept 45% of his promises, compromised on 24%, and has 4% in the works. Out of 532 promises, 390 have been either accomplished in some manner or are being worked on as we speak (or 73%). Also, you should take note of how the Obameter measures progress: it requires tangible results to count as finished, rather than intentions. At least some of the ones listed in "promises broken" are ones that have stalled due to an inability to get them through Congress.
In short, your post is simply not congruent with the facts.
