If Obama and McCain weren't in the race, who would you want to see in their place?

OK, pretend senators Obama and McCain don't exist for a second. Who would you like to see run for president for both the Democratic and Republican parties? Answer for both parties. Give me two names... I would like to see Mike Huckabee or Rudy Giuliani for the Republican party and either Ted Kennedy or Joe Lieberman for the Democratic party.
