2018 St. Louis County Executive election

The 2018 St. Louis County Executive election took place on November 6, 2018. Incumbent County Executive Steve Stenger ran for re-election to a second term. He faced a difficult challenge from businessman Mark Mantovani in the Democratic primary, and won renomination with just 50.3 percent of the vote. In the general election, Stenger was opposed by Republican Paul Berry III, a political commentator and bail bondsman. In a contrast to Stenger's close election in 2014, he won re-election in a landslide, receiving 57 percent of the vote to Stenger's 37 percent. However, Stenger did not serve out his full term as County Executive, resigning in 2019 after being indicted for bribery and fraud.
