A primary election is used to narrow the field of candidates for certain positions or to determine the political party nominees before a general election. Missouri has an open primary. Voters are not required to be affiliated with a political party in order to vote in that party’s primary. Voters are also able to declare any party at the polls regardless of previous party affiliation. 

In the Missouri primary, voters throughout the state will select one candidate to serve in the U.S. Senate, eight candidates to serve in the House of Representatives, a state auditor, 17 state senators, and 163 state representatives. Clay County, Jackson County, Platte County, and the city of St. Louis have several municipal positions that will be on the ballot. Using Ballotpedia’s sample ballot lookup tool, voters can find the candidates that will be on their ballot on Aug. 2.
