Elaine: Kerry
Jerry: Bush
Kramer: Kerry or Nader
George: Kerry
Poppy: Bush
Jackie Chiles: Kerry
Peterman: Bush
Mr. Pitt: Bush
Kenny Bagna (sp?): Bush
Jerry's Parents: Kerry
George's Parents: Estelle Kerry, Frank doesn't vote (he is mad that he could never be president because he was born in Italy, so he doesn't vote)
Soup Nazi: Bush
Who else is there?
But the GOP, as everyone knows, is run by an alliance of two groups: craven plutocratic Jews and Mafioso. So, I'd imagine Soup Nazi is torn by his allegiances.
I also disagree with your assessment of Kramer. I'd also read that he was based on a real Libertarian.
Elaine of course is a self-righteous, greedy, impatient bitch. So, yeah, she's probably a democrat. Jerry? Anyone's guess. Given that he generally whines and bitches about everything, I'd guess a democrat as well. Neumann is clearly a democrat. Poppy, for reasons stated above Re: Soup Nazi is almost certainly a republican. Mr. Pitt? Very wealthy and very old. No doubt a Rockefeller Republican. Peterman? Same as Pitt.
Chiles: Can there be any doubt? This guy's about as Democrat as they come. Bagna? Hard call. The italian name leads one to believe he just might be a bushie, but that's pretty generic.
You forgot the bra-less wonder. I'd register her as a Kerry woman as well.
