Before the smoke began to clear over New York after September 11, 2001, Rudolph Giuliani devised a plan that would halt impending mayoral elections and keep him in power beyond the term-limited end of his second and final four years as mayor.
The contemporary account of Giuliani's power grab written by Wayne Barrett of the Village voice is here.
To accomplish this coup Giuliani would have to persuade the New York candidates for mayor to postpone their ambitions and agree to appoint Rudy Dictator of New York.
On the Republican side, Michael Bloomberg didn't mind waiting a couple months. He was Giuliani's endorsed successor and basically the only Republican running.
It was the Democrats, of course, that Rudy needed on this one. The two major Democratic candidates were Mark Green, the city's public advocate, and Fernando Ferrer, the Bronx borough president. Their primary had been scheduled for 9/11 and then rescheduled to October. Green ended up winning the nomination and then losing to Bloomberg. (Green has since bought the progressive radio network Air America.)
