South Dakota voters can register online through the South Dakota Secretary of State's website at sdsos.gov/elections-voting/voting/register-to-vote.aspx, which requires a valid South Dakota driver's license or state ID number. The voter registration deadline is 15 days before any election. New residents can also register in person at the Hamlin County Auditor's office or at their polling place on Election Day with proof of residence. Municipal elections for mayor and city council positions typically occur in April of odd-numbered years (next scheduled for April 2025 and April 2027), with candidate filing periods in late February or early March. Information about city candidates, local ballot measures, and municipal election dates is available through Castlewood City Hall at (605) 793-2231 and the County Auditor's office. Residents can find their assigned polling place by visiting the South Dakota Voter Information Portal at sdsos.gov/elections-voting/voting/polling-place-information.aspx or by contacting the Hamlin County Auditor directly. Polling places are organized by precinct, with voters typically casting ballots at a location within the city limits. In the November 2024 general election, Hamlin County reported voter turnout of approximately 73% of registered voters, reflecting strong civic engagement consistent with South Dakota's historically high participation rates, particularly in presidential election years. Looking ahead to the November 3, 2026 general election (South Dakota holds general elections on the first Tuesday after the first Monday in November of even-numbered years), local voters will decide several significant races. South Dakota's gubernatorial election will be on the ballot in 2026, as governors serve four-year terms with the last election in 2022. The U.S. Senate seat currently held by one of South Dakota's senators will be contested in 2026 depending on the election cycle (South Dakota's two Senate seats are Class II and Class III). The U.S. House of Representatives at-large seat representing all of South Dakota will be on the ballot. South Dakota state legislature seats for District 3 (which includes Hamlin County) will be contested, including one State Senate seat and two State House seats, all serving two-year terms. Hamlin County offices up for election in 2026 include County Commissioner positions (five commissioners serving staggered terms), County Auditor, Register of Deeds, State's Attorney, Sheriff, and other constitutional offices depending on the election rotation. South Dakota offers no-excuse absentee voting; any registered voter may request an absentee ballot through the Hamlin County Auditor without providing a reason. Absentee ballot applications can be submitted online, by mail, in person, or by fax to the Hamlin County Auditor's office, and must be received by 5:00 PM the day before the election. Completed absentee ballots must be received by the Hamlin County Auditor by 7:00 PM on Election Day. South Dakota public records law provides that voter registration information including names, addresses, and voting history (which elections a person voted in, but not how they voted) is publicly available, though use of this information for commercial purposes is restricted. Campaign finance reports for candidates and political committees are filed with the South Dakota Secretary of State and are searchable online at sdsos.gov/campaign-finance. Precinct-level election results are posted by the Hamlin County Auditor following certification and are also compiled statewide by the Secretary of State's office.
