Incumbent Democrat Alan Butkovitz (who is spoken of frequently as a potential mayoral candidate in two years) is seeking his third term in office. While he has the backing of the Democratic City Committee, he does face two primary challengers: 44-year-old Brett Mandel, a former aide to the previous controller Jonathan Saidel; and 60-year Mark Zecca, an attorney who had spent years with the city’s Law Department and who is the son of Tony Zecca, a former aide to the late mayor Frank Rizzo.

On the Republican ballot for Controller, 30-year-old Terrance Tracy is unopposed.
