Hey, I have to say, Barrack was cool with his answer on this---in this area, I give him credit for taking the high road.
He can claim no such thing. As someone has mentioned, there is a well designed democrat attack machine (thanks bill and hillary) which does the dirty work for obama. There is no need for him to lift a finger. You will never hear him throw the Daily Kos under the bus because he believes in what they do.
Obama and high road can never be used in the same sentence unless you have a grin on your face.
