Premise: New York Mayor Randall Winston needs help running the city. So, for much of the series, he counts on Deputy Mayor Mike Flaherty to help him. Flaherty, usually a man who is calm and organized, can ``spin'' out of control when it comes to his personal life, the ditzy mayor, and his abnormal co-workers. For the show's final two seasons, Flaherty is replaced as deputy mayor by Charlie Crawford after Michael J. Fox, who played Flaherty, was diagnosed with Parkinson's disease and left the show.
