A special election for Illinois Comptroller took place on November 8, 2016. After comptroller Judy Baar Topinka died shortly after her reelection in 2014, Republican Governor Bruce Rauner appointed Leslie Munger, a former business executive and unsuccessful 2014 nominee for the Illinois House of Representatives, to fill her seat at the beginning of his term in 2015. Per Illinois state law, a special election was held to elect a comptroller to finish Topinka's term. Munger ran as the Republican nominee against Democratic Chicago City Clerk Susana Mendoza. State Senator Daniel Biss ran for the Democratic nomination, but dropped out in November 2015.
