I disapprove of his tenure for many reasons:
1. Clearly believing, on issue after issue after issue, throughout his term, that partisan democrats have a monopoly on good ideas, despite saying that he doesn't believe such a thing.
2. Preferring defaulting on our debt over negotiating.
3. His refusal to pass stimulus for the middle class, instead catering to the moguls and big banks on wall street, resulting in a recovery that has been extremely sluggish and, six years into his presidency, leaves underemployment in double digits (it was ~8% before the recession), and wages/labor participation much too low.
4. Refusing to work with republicans when he passed his health care reform, despite promising he would, and then passing a law too long for anyone to read, filled with terrible provisions such as the 30 hour work week and the medical device tax.
5. Lying about certain provisions of said health care law over and over and over again, then trying to deny having lied about them, and refusing to get the website properly betatested.
6. Refusal to permantely cut overall military spending or push for fair trials for Guantanamo bay prisoners, despite promising to do so.
7. Taking too long to end the wars in Iraq and Afghanistan, which have not accomplished enough to merit being stretched out as long as they are/were.
8. His "policies are on the ballot" 2014 gaffe, which may have sunk Begich and Hagan, both of which I really like.
9. Benghazi (LOL)
Yay republican talking points! Although I'd forgive you if you disapproved of the GOP congress even more, seeing as half those points are the GOP's fault (bolded), and some more on top of that.
