While Edwards continues to drive himself off Hillary’s Christmas card list, Barack Obama (apparently with the support of the shaggy-headed disinterested youth vote) has returned to his message of change. Obviously, he’s saying that Hillary is business as usual, but it’s in a much prettier package. The Edwards fit is the last gasp of his political career, but Obama knows that he’ll have another chance if it doesn’t work out in ’08. Lets hope he sticks to the positive campaign message.
