The Bon Homme County Auditor's Office administers all elections for Tyndall and the surrounding area. Located at 300 West 18th Avenue, Tyndall, SD 57066, the office can be reached at (605) 589-4213. The County Auditor handles everything from voter registration and ballot preparation to polling place management, absentee voting, and certification of results. Election information, sample ballots, and polling locations are available through the county or the South Dakota Secretary of State's website.
South Dakota residents can register to vote online at sdsos.gov/elections-voting/voting/register-to-vote.aspx, by mail using a voter registration form, or in person at the County Auditor's office. The deadline falls 15 days before any election. Voters must provide either a valid driver's license number or the last four digits of their Social Security number when registering. Basic requirements include U.S. Citizenship, being at least 18 years old by election date, and South Dakota residency. The state conducts open primaries, so party registration isn't required - voters simply choose which party's primary ballot to cast. Municipal elections in Tyndall determine who serves as mayor and on the city council. These contests typically occur in April of odd-numbered years, with the next scheduled for April 2025 and another following in April 2027. Council seats rotate on staggered terms to ensure continuity. Residents can learn about local candidates, filing deadlines, and municipal ballot questions by contacting Tyndall City Hall at (605) 589-3525. Local option issues such as liquor licensing or municipal bond questions sometimes appear alongside candidate races. To locate their assigned polling place, residents should contact the Bon Homme County Auditor or use the South Dakota Polling Place Locator at sdsos.gov. Assignments are based on residential address and precinct boundaries. Voters in Tyndall typically cast ballots at the courthouse, community centers, or school facilities. Polls open at 7:00 AM and close at 7:00 PM Mountain Time on election day - an important detail since Bon Homme County observes Mountain Time, unlike much of eastern South Dakota which uses Central Time. The state makes election records readily accessible to the public. Voter registration lists are available to candidates, political parties, and the public for election related purposes through the Secretary of State's office. Campaign finance reports for state and county candidates must be filed with the Secretary of State and can be searched online at sdsos.gov, revealing contributions and expenditures for candidates and committees. Candidate filings, statements of organization, and petition signatures are all public records. After certification, precinct-level election results are published by the County Auditor and compiled statewide by the Secretary of State, with detailed results available on the Secretary of State's website. The county followed the pattern of rural South Dakota, voting heavily Republican in federal races while sometimes showing more competitive results in local contests. South Dakota's gubernatorial race heads the ticket, with voters selecting the governor and other constitutional officers including attorney general, secretary of state, auditor, treasurer, commissioner of school and public lands, and public utilities commissioners. State legislative seats are elected in even-numbered years, so Bon Homme County's positions in District 17 for both the State Senate and House will appear on the ballot. County-level races include elections for county commission seats, county auditor, register of deeds, state's attorney, sheriff, and other county offices depending on term schedules. South Dakota offers no-excuse absentee voting, meaning any registered voter may request an absentee ballot without providing a reason. Requests can be made through the County Auditor's office by mail, in person, or through the online absentee ballot application portal at sdsos.gov. While the deadline to request an absentee ballot is typically the day before the election, requesting earlier is strongly recommended. Completed absentee ballots must be received by the County Auditor by election day - postmarks do not count. The state does not conduct all-mail elections, so most voters still cast ballots in person at polling places, though absentee voting has grown in popularity particularly since 2020.
