The Bates County Clerk's Office is the election authority for Rockville voters. Located at 1 North Delaware Street, Butler, MO 64730, the office can be reached at (660) 679-3371 and posts election information on Bates County's official website at www.batescounty.net.
Missouri residents can register to vote online through the Missouri Secretary of State's website at www.sos.mo.gov/elections/goVoteMissouri or submit a paper application to the Bates County Clerk. Applicants must be U.S. Citizens, Missouri residents, at least 17.5 years old (though 18 to actually vote), and not currently serving a felony sentence. Registration must be completed by the fourth Wednesday before any election to be eligible. Missouri requires photo identification such as a driver's license, non-driver's license, military ID, or passport; those without photo ID may cast a provisional ballot. As an unincorporated community, Rockville does not hold municipal elections for mayor or city council since no city government exists. Residents vote in county, state, and federal elections instead. Bates County holds elections for County Commissioners, Sheriff, Assessor, Clerk, Collector, Treasurer, Coroner, and Prosecuting Attorney, typically on a four-year cycle with offices rotating election years. Polling place assignments can be found by contacting the Bates County Clerk or using the Missouri Secretary of State's polling place lookup tool at www.sos.mo.gov/elections/pollingplacelookup. Under Missouri's Sunshine Law (Chapter 610 RSMo), voter registration lists are public records available for inspection, though restricted to election, political, and governmental purposes. Campaign finance records are maintained by the Missouri Ethics Commission at www.mec.mo.gov and are fully searchable online. Candidate filings for local offices are available through the Bates County Clerk, while state and federal filings are accessible through the Secretary of State. Precinct-level election results become public records published by the Bates County Clerk following certification. No U.S. Senate seat from Missouri is scheduled for election in 2026, as the state's senators are elected in presidential years. State-level races will include all 163 Missouri House of Representatives seats (two-year terms) and approximately half of the 34 Missouri Senate seats (four-year staggered terms). County voters will elect county officials whose terms expire in 2026, potentially including County Commissioner positions and various township offices. Depending on the election cycle, the Presiding Commissioner and associate commissioner positions may be contested. Any local ballot measures, school board positions for Butler R-V Schools, or special district elections will also appear on the ballot. Missouri offers absentee voting by mail for voters who meet specific qualifications including being absent from their jurisdiction on Election Day, incapacity or confinement due to illness, religious belief or practice, employment as an election authority, or incarceration (if otherwise eligible to vote). Absentee ballot applications must be submitted to the Bates County Clerk by the second Wednesday prior to the election. No-excuse absentee voting is not permitted in Missouri. The state does not have permanent mail-in voting; each election requires a new application unless the voter is permanently disabled.
