I think Kerry lacks the balls, the guts, the common sense, the decency, and the honesty to concede in a timely manner. I'm not sure how long he'll wait, and whether or not he'll actually make an effort in court I don't know, but I think he may.
I think Bush is showing that he is the better man by not claiming victory, and allowing Kerry every opportunity to do the right thing.
I just don't think Kerry will do the right thing. Whether he refuses to concede on his own, or at the wishes of the Democratic party, the decision reflects on him, and shows his true colors.
