I am ready to stand corrected. I do not recall this "pledge," vaguely cited (again) by the Washington Post:
Obama regularly talks about his desire to find bipartisan consensus, even if he has not delivered on his 2008 pledge to change politics in Washington.
What I recall is Obama's pledge to strive for greater comity and fewer fanatical fevers and less diagnosable insanity and at least some workable semblance of bipartisan consensus. He promised to try. Did he promise delivery?
Perhaps he did, perhaps somewhere in some speech he failed to qualify what would amount to--even in the heat of self-inflated campaigning--an absurdly hubristic, triumphalist pledge. But I sure don't recall it.
Nonetheless the claim is made repeatedly by the Beltway press. Might they, every now and then, provide a quote? Please?
