Did Pres. Obama ever use the term "Post Partisan?

[lxlxlxl]

Sometimes the press just runs and runs with an idea that has no basis in fact. Take the "poor people caused the credit crunch' meme that has become national truth. Now I know Obama was extremely gracious towards Bush during the election year, and this idea of 'post partisan' was tacked onto 'postracial' for no reason. Now 'postpartisanship' is treated as absolute truth. Did he ever use that word? Where did this easily repeated phrase come from?

Was it something that grew out of his lack of viciousness in attacking the GOP? or targeting Bush for creating the mess we are in?
