Which politician appears in the Giuliani version of 'The Non-Fat Yogurt'?

Which politician appears in the Giuliani version of “The Non-Fat Yogurt”? Rudy Giuliani appears in that version.

“The Non-Fat Yogurt” was written around the 1993 New York City mayoral election between incumbent David Dinkins and Republican challenger Rudy Giuliani. The episode’s fictional yogurt scandal affects the election, allowing the comedy to connect the characters’ obsession with frozen yogurt to a real political contest.

Because the episode was scheduled to air only two days after the election, Seinfeld’s producers prepared alternate versions. The Giuliani version used Giuliani’s victory and included a cameo by Giuliani as himself. He filmed his scenes on the morning after his election victory, making the production unusually close to real-world events.

The Dinkins alternative substituted references and used an actor portraying a campaign spokesman rather than Dinkins himself. That production wrinkle can cause confusion, but the politician appearing in the broadcast Giuliani version is unequivocally Rudy Giuliani.
