I wish I had the artistic ability to draw a political cartoon because after watch most of the debate this is the feeling I have. In my head it is a picture of Senator McCain standing like a monster pointing a finger down at Senator Obama and Obama pointing a finger back at McCain:
McCain is saying: Pork Barrel spending is the problem (while he is taking money from a fat lobbyist with his other).
Obama is saying: The washington machine is the problem (with a machine in his other hand entitled the grassroots machine).
I think that sums up the debate in as few a words as possible.
