Sumner, Missouri voters are served by the Chariton County Clerk's Office, which administers all elections for the area. The Chariton County Clerk is located at 1000 St. Louis Avenue, Keytesville, MO 65261, and can be reached at (660) 288-3602. The Clerk's office maintains voter registration rolls, manages polling places, counts ballots, certifies election results, and provides absentee voting services. Sumner residents can register to vote online through the Missouri Secretary of State's website at https://www.sos.mo.gov/elections/goVoteMissouri/register, by mail using a voter registration application, or in person at the County Clerk's office. Missouri law requires voters to register at least 28 days before an election. Acceptable forms of identification for in-person voting include a Missouri driver's license, non-driver ID, military ID, passport, or other government-issued photo ID. Because Sumner is unincorporated and has no municipal government, there are no city council elections, mayoral races, or local ballot measures specific to Sumner. Elections in the area focus on county offices (County Clerk, Sheriff, Assessor, Collector, Coroner, Presiding and Associate County Commissioners), state legislative seats (Missouri House District and Senate District), statewide offices (Governor, Attorney General, Secretary of State, State Auditor, State Treasurer), and federal races (U.S. President, U.S. Senate, U.S. House). Sumner voters can find their assigned polling location by visiting https://voteroutreach.sos.mo.gov/portal/ or by calling the County Clerk. In the November 2024 presidential election, Chariton County reported strong turnout with approximately 60 to 65 percent of registered voters casting ballots, consistent with historical patterns for rural Missouri counties in presidential cycles. For the November 3, 2026 general election, Chariton County and Sumner voters will decide several important races. Missouri does not have a U.S. Senate seat up for election in 2026, but voters will elect a new Governor (the current term expires in January 2025, with the next gubernatorial election in 2024 and again in 2028; however, all Missouri state executive offices elected in 2024 serve four-year terms, so only legislative and county races will appear in 2026). Voters will elect members of the Missouri General Assembly, including their State Representative and potentially their State Senator depending on district rotation. All county offices are also up for election in 2026, including Sheriff, County Clerk, Assessor, Collector, Treasurer, Coroner, Prosecuting Attorney, and County Commissioners. Missouri allows absentee voting for any registered voter who requests a ballot. Absentee ballot applications can be submitted online, by mail, or in person to the Chariton County Clerk, and ballots must be requested no later than the second Wednesday before the election. Voted ballots must be returned by mail (postmarked by Election Day) or delivered in person to the County Clerk's office by 7:00 p.m. on Election Day. Missouri election records that are public include voter registration lists (available for purchase by campaigns and political organizations), campaign finance reports filed with the Missouri Ethics Commission (searchable at https://mec.mo.gov/), candidate filings and petitions, and precinct-level election results, all of which are accessible through the County Clerk or Secretary of State. Missouri does not permit online ballot tracking for all voters but does allow absentee voters to check ballot status through the Secretary of State's portal.
