Does my party affiliation matter when I vote in the primaries?
South Dakota’s Democratic primary is open to registered Democrats and independent/no party affiliation (NPA) voters, but not Republicans. Its Libertarian primary is open to voters registered as Libertarian, independent or NPA. Its Republican primary is limited to registered Republicans.
Independent or NPA voters who plan to vote absentee must choose a party ballot when filling out an absentee ballot application. Voters who fail to designate a party ballot will be sent a nonpolitical ballot, which includes only candidates running without a party affiliation and/or local ballot measures.
How can I get an absentee ballot?
Any registered voter can request an absentee ballot. Note that absentee ballot application forms are valid for one calendar year.
Apply online, by mail or via an authorized messenger, if eligible.
- By mail: Download and complete an absentee ballot application form. Mail your original, signed application to your county auditor's office. Attach a copy of an acceptable form of ID — such as a South Dakota driver's license, a South Dakota nondriver ID card, passport or tribal photo ID — to your application. Or complete a notarized oath on the form (Section 7) swearing the information is true and correct.
- In person: Fill out an absentee ballot application form at your county auditor's office. Bring an acceptable form of ID. You can complete your absentee ballot application and mark your ballot at the same time.
- Using an authorized messenger: If sickness or disability keeps you from the polls, you can apply for an absentee ballot via an authorized messenger. The authorized messenger may pick up and return your ballot to the county auditor for you. Download, print and complete the absentee ballot application form, including the authorized messenger request section.
Your application is due by mail or in person by 5 p.m. the day before an election. If you’re returning your application via an authorized messenger, it is due by 3 p.m. on Election Day. Ballots are mailed within 48 hours of an application’s receipt.
Only voters covered under the Uniformed and Overseas Citizens Absentee Voting Act can submit their application for an absentee ballot via fax or email.
How do I submit an absentee ballot?
Return your completed absentee ballot:
- By mail: Follow the instructions that accompany your absentee ballot, then mail your ballot with proper postage to your county auditor’s office.
- In person: Drop off your completed ballot at your county auditor’s office or at a secure drop box, if your county uses them. Absentee ballots cannot be returned to your polling place on Election Day. Contact your county auditor’s office for drop box locations.
- Using an authorized messenger: All voters can have someone deliver their ballot to the correct county auditor’s office or a secure drop box, if offered.
Completed absentee ballots must be received on Election Day with sufficient time for election officials to deliver them to the corresponding polling locations before the polls close. Contact your county auditor to determine the deadline.
Can I track my absentee ballot?
Track your ballot using the state’s voter portal.
Can I vote in person before Election Day?
South Dakota doesn’t offer early in-person voting, but you can go to your county auditor's office to complete and submit an absentee ballot in person.
Do I need identification to vote?
Yes. All voters applying for an absentee ballot or voting at a polling place on Election Day need to show an approved photo ID, including a state-issued driver’s license, state-issued student ID, U.S. passport or tribal ID.
If you do not have an approved photo ID while voting in-person absentee or at the polls, you may complete a personal identification affidavit and still vote a regular ballot. This affidavit may not be used as a substitute for the ID requirements for the absentee ballot application.
