Personally, I don't want Obama re-elected.
It has nothing to do with Parties, I believe that there shouldn't be any parties. A man should have to run on his own platform, not a platform create by a group.
Obama didn't accomplish many of the things he promised (but honestly, who did?) and I respect that he passed things like National Health Care, though I disagree with it as a whole.
Presidents are supposed to be representative of the people who elected him and he was indeed elected and it appears he is doing what the people who put him in office required. So, my vote will go to someone else, but it's not personal. He's doing what he's supposed to, representing the people who voted him in the manner that they desire him to, I merely disagree with his opinions (which he, as well as his supporters, are entitled to and welcome to express).
