The 1975 mayoral election was held to select the 37th mayor of San Francisco, and was held in two parts. In the November regular election, then-Speaker of the California State Assembly George Moscone placed first with conservative city supervisor John Barbagelata second and moderate supervisor Dianne Feinstein coming in third.[1] Moscone and Barbagelata thus both advanced to the mandated runoff election in December where Moscone narrowly defeated the conservative supervisor by 4,400 votes,[2] a margin of less than 1%.[1]
For the rest of his life, Barbagelata maintained that the People's Temple religious cult, led by Jim Jones, committed election fraud by bussing in out-of-town church members to double and triple vote for Moscone under the registrations of dead voters.[2]
