A friend, Guy Davis, said that after watching last week's health care summit, "Professor Obama managed to sweep me once and for all into the anti-Obama camp from my previously neutral stance. When he said 'We're not campaigning any more. The election is over,' in response to McCain's attacks on the [closed door nature of the original negotiations as well as the] earmarks in the health care bills, I took it as the most egregious rejection of any responsibility for his campaign promises that I have ever heard from a politician."
Most of us had interpreted Obama's comment as mere snippiness. But Guy is right: underlying Obama's comment is an assumption -- almost a tacit admission -- that what one says during a campaign has little to do with what one will do while governing.
Obama has certainly demonstrated that this past year.
