Try this: If you listen to the candidates' speeches and every time they mention each other, you insert Superman or Batman's name, or whichever superhero you prefer, and every time they mention Saddam Hussein or Osama Bin Laden, or terrorism, substitute Lex Luthor or, I don't know, The Riddler. Dick Cheney, is always Darth Vader, though.
For instance: "When Superman had Lex Luthor cornered in the Fortress of Solitude, he didn't use the best soldiers in the world to flush him out. Superman turned to Mr. Mxptlyx, and Lex Luthor got away." Or whatever. 'S fun.
