It comes from Obama himself:
Given how much stuff was coming at us, we probably spent much more time trying to get the policy right than trying to get the politics right... I think anybody who's occupied this office has to remember that success is determined by an intersection in policy and politics and that you can't be neglecting of marketing and PR and public opinion.
David Corn complains that this is the kind of self-criticism that does not help before an election, and that in arguing that his biggest error was under-estimating Republican obstructionism, the president cannot also argue that he can work with the GOP, if necessary, in the next two years.
I don't agree. This kind of quote is why I still believe, despite my frustrations in some areas, that Obama is the best option we've got and we're lucky to have him. I want a president who can acknowledge error, is not cocooned, can speak publicly about this, and is unafraid of self-criticism. Isn't that why so many of us supported him in the first place?
And, look, another reason we supported him is that after eight years of Rove, we actually wanted a president who got the policy right. I think his success in this is quite remarkable, in fact.
