I don't read that much in to it really. Hackett is representing a Marine officer who is in the Haditha chain of command. It is in his client's best interests to get Murtha to shut his yap.
Since the race is DeWine/Brown, I suspect Mike DeWine will win by 10 points. had it been Hackett, it would have been close, but Hackett would have had another one of those "winning" loses... But the interesting thing is to ponder what exactly Ohio's Howard Dean would have YEAAAAAARGH!ed at because you know it was bound to happen.
