I gave money to Barack Obama for his campaign. I stood up for him to Hillary Clinton supporters who were insistent that his presidency was going to be disastrous and that it was better to elect John McCain than Barack Obama. I voted for him and I used my voice to encourage others to vote for him. As of right now, I'm planning on looking very closely at the entire field of potential Democratic challengers to his candidacy in 2012, because frankly I think that Barack Obama has let me and every one who worked so hard to get him elected down.
I say this for three reasons; the failure to push for meaningful healthcare reform in the face of the health care mandate, his failure to follow through on his promises to repeal don't ask don't tell; and his failure to understand that the people opposed to him are not dealing in good faith and as such he needs to do everything he can to minimize their impact rather than pretending he is working with adults who actually care about anything other than playing a petty game of political one upsmanship.
If he's playing a long game that I don't yet see, he can still win me back.
As of right now, I'm skeptical that he deserves a second term.
Less than a year into his first term, that's a bad sign.
