Boy, this forced me to do some research into the various third-party candidates.
Vladimir Lenin -> Roger Calero
Joseph Stalin -> Roger Calero
Leon Trotsky -> Bill Van Auken
Nikita Khrushchev -> Roger Calero
Leonid Brezhnev -> Roger Calero
Mikhael Gorbachev -> Walt Brown, maybe Nader or Cobb
Nicolae Ceausescu -> Roger Calero
Enver Hoxha -> Roger Calero
Adolf Hitler -> Write-in: David Duke
Francisco Franco -> Write-in: Pat Buchanan
Benito Mussolini -> Write-in: Pat Buchanan
Evo Morales -> Walt Brown, maybe Calero
Fidel Castro -> Roger Calero
Hugo Chavez -> Roger Calero
You didn't really expect that I would answer anyone of them with "Bush" or "Kerry"?
