2018 United States Senate election in Missouri


The 2018 United States Senate election in Missouri took place on November 6, 2018, to elect a member of the United States Senate to represent the State of Missouri, concurrently with other elections to the United States Senate, elections to the United States House of Representatives, and various state and local elections, including Missouri's quadrennial State Auditor election.
Incumbent senator Claire McCaskill ran for re-election in a primary field of eight Democrats. Eleven Republicans vied for their party's nomination which went to State Attorney General Josh Hawley, who filed notification in August, 2017, that he had formed an exploratory campaign committee for the seat.
The candidate filing deadline was March 27, 2018, and the primary election was held on August 7, 2018. On November 6, 2018, Hawley was elected with 51.5% of the vote, to McCaskill's 45.4%, resulting in Republicans holding both Senate seats in Missouri for the first time since McCaskill took office in 2007.

Sen. McCaskill conceded a few hours after the polls closed on Election day. Despite performing strongly in the St. Louis suburbs, she ran well behind her 2012 vote in Southeast Missouri, especially in the Lead Belt and the Missouri Bootheel. She also ran poorly in the northern part of the state. Despite McCaskill's loss, Missouri Democrats held the other statewide office that went up for election in this cycle, the office of Missouri State Auditor. Democratic incumbent state auditor Nicole Galloway, who had been appointed to the post in 2015 by then-Gov. Jay Nixon following a vacancy, won a full term in the 2018 State Auditor election.
