The last minute undecided voters usually fall heavily against the incumbent, for the simple reason that if they liked him they would have sided with him long ago. For Bush to be in a good posistion, he needed to go into this final strech with a lead of some sort.
It is begining to look like Kerry might hold enough electorial votes to make any court challenges pointless. If Kerry can get far enough ahead that even even the court ruling against him in 2 or more states won't chance the election, the Bush will have little choice but concede.
