Obama has obviously not fulfilled his duties as president. Yes, I do agree that it was a major accomplishment to take out Osama Bin Laden, but that is about all he has done. If you haven't noticed, we are in about 17 billion, 384 Million dollars in debt. He also is losing ground rapidly with the Speaker of the House.
We may be in debt, but just remember that that debt was not started by Obama. He has supported important social issues such as gay marriage and abortion, started the removal of troops from Afghanistan, implemented a flawed, but generally good bill ensuring that we, as a society, do not let someone die just 'cuz they don't have health insurance. I'm not too knowledgeable on this, but he has implemented/plans to implement several beneficial environmental bills as well, which is something that is a top priority nowadays lest the level of C02 release becomes so large that methane burps start coming from the ocean, the Earth starts heating up, etc. Feel free to correct me and refute my arguments.
