Thomas Richards Democratic Thomas Richards Democratic Pre-consolidation: Post-consolidation: Pre-consolidation: Post-consolidation: The 2011 Rochester mayoral special election took place on March 29, 2011, in the city of Rochester, New York, United States.

Thomas Richards was elected over former mayor William A. Johnson Jr. to serve for the remainder of the term.

Incumbent Democratic Thomas Richards had been sworn in as interim mayor after Robert Duffy was elected lieutenant governor in 2010, previously having served as the City of Rochester Corporation Counsel and subsequently deputy mayor.

The immediacy of the election precluded the possibility of primaries, so candidates were chosen directly by the party leaders.

Having decided to contest the special election for the rest of Duffy's term, Richards resigned to ensure he could run without violating terms of the Hatch Act, which could have jeopardized federal funding.
