Anyone who is not in politics.
Rush? Beck? Olberman? Maher? Coulter? Cher?...
Maher ... maybe, Cher ... that would at least be interesting since she's been through almost all the dirt already. Penn J. would be my first choice though, or Teller, but Teller's rich already. I'd say George Carlin but he's passed on sadly. Though if I had to choose from the same quality as the politicians, I'd pick Cthulhu ... at least you'd go mad before he destroys the country.
Maher? Surely you jest... and Cthulhu isn't real...
