For the past eight years Green and Giuliani have been the Muhammad Ali and Joe Frazier of New York, brawling from one end of the five boroughs to the other. Giuliani, notoriously thin-skinned, couldn't stand Green sniping at him over police brutality and other issues, hated that he couldn't fire Green, and was peeved that Green—who didn't have to do anything but grandstand—was as popular as he was. Giuliani's agencies did everything they could to block Green's work. In 1999, Giuliani tried to amend the city charter to prevent Green from succeeding him if he were elected to the Senate. Green, in turn, was enraged by Giuliani's imperiousness, tendency to suppress dissent, and indifference to victims of police brutality. Green has repeatedly sued Giuliani to get access to public records—"I'm 4 and 0 against him," Green gloats. It surely irks Giuliani that he will be succeeded by the rival he has tried hardest to destroy. And it surely irks Green that he will be expected to govern like the mayor he detests.
