2018 San Francisco mayoral special election
A special election was held for Mayor of the City and County of San Francisco on June 5, 2018. The winner of the election will serve until 2020, filling the unexpired term of Ed Lee, who was elected in 2011 and 2015, and died in office on December 12, 2017. Upon Lee's death, London Breed, President of the San Francisco Board of Supervisors, became Acting Mayor of San Francisco, but a vote of six supervisors replaced Breed with Supervisor Mark Farrell. The mayoral election was held concurrently with the statewide direct primary election. In San Francisco, the election for the eighth district member of the Board of Supervisors was also on the ballot.
Joel Engardio
Engardio was appointed to the San Francisco Democratic County Central Committee in July 2015 and served until July 2016. The DCCC is the governing body for the local Democratic Party.
In 2016, Engardio was the only candidate endorsed by both the San Francisco Chronicle and San Francisco Examiner in his race for the San Francisco Board of Supervisors. Engardio finished second in a field of five candidates. He was the first openly gay supervisor candidate to run in San Francisco’s conservative District 7, where half the voters in some precincts supported a 2008 ban on gay marriage.
Engardio serves on the board of directors of San Francisco's Alice B. Toklas LGBT Democratic Club  and the political action committee San Francisco Moderates.
