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.
2015 San Antonio mayoral election
Julian Castro, who was first elected mayor in the 2009 mayoral election, was selected in 2014 to become the next United States Secretary of Housing and Urban Development. Upon that announcement, State Representative Mike Villarreal immediately announced he would run to succeed Castro in the 2015 election. Once Castro was confirmed by the U.S. Senate, the San Antonio City Council selected Ivy Taylor as interim mayor by a third-round unanimous vote becoming the city's first African-American mayor.
