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.
Moscone–Milk assassinations
The Moscone–Milk assassinations were the killings of San Francisco Mayor George Moscone and San Francisco Supervisor Harvey Milk, who were shot and killed in San Francisco City Hall by former Supervisor Dan White on November 27, 1978. White was angry that Moscone had refused to reappoint him to his seat on the Board of Supervisors, from which he had just resigned, and that Milk had lobbied heavily against his reappointment. These events helped bring national notice to then-Board President Dianne Feinstein, who became the first female mayor of San Francisco and eventually U.S. Senator for California.
