State Threat Profile

South Dakota is a solidly Republican state with no competitive federal races expected in 2026. The most significant election integrity concern is voting access for Native American communities on the state’s nine reservations. Reservation residents face some of the most severe geographic barriers to voting in the country — distances of 50 miles or more to the nearest polling place are common, roads are often unpaved and impassable in winter, and USPS delivery is unreliable. South Dakota requires photo ID at the polls, with tribal IDs accepted. The state offers no-excuse absentee voting and limited early voting. Gov. Rhoden, who succeeded Noem, has not been a significant actor on election policy.

Key Officials

• Governor: Larry Rhoden (R) — succeeded Kristi Noem (now DHS Secretary); has not been a primary actor on election policy
• Secretary of State: Monae Johnson (R) — chief election administrator; has promoted election security measures and voter roll accuracy
• Attorney General: Marty Jackley (R) — has not focused significantly on election issues

Voter Defense Basics

For Every Voter

1. Verify your registration — South Dakota’s registration deadline is 15 days before the election.

1. Know your ID requirements — South Dakota requires a photo ID at the polls. Accepted: South Dakota driver’s license, state ID, US passport, military ID, tribal ID, or student ID from a South Dakota high school or accredited institution. If you lack qualifying ID, you may sign a personal identification affidavit and cast a regular ballot.

1. Absentee voting — South Dakota allows no-excuse absentee voting. Request your ballot from your county auditor.

→ Absentee ballots must be received by the close of polls on Election Day. → Mail at least 14 days before Election Day — USPS service on and near reservations is particularly slow.

1. Early voting — In-person absentee voting is available at your county auditor’s office beginning 46 days before the election.

1. Native American voters: Tribal IDs are accepted at the polls. If distance to your polling place is a barrier, request an absentee ballot well in advance and return it as early as possible. Contact the Four Directions voter assistance line for help.

For Organizers and Lawyers

1. Prioritize Native American voter access on reservations — the most pressing voting rights issue in South Dakota. Distances on Pine Ridge and Rosebud reservations can exceed 100 miles round-trip to a polling place. Provide transportation, encourage early absentee voting, and advocate for additional polling locations or satellite offices.

1. Monitor absentee ballot rejection rates — particularly for ballots from reservation zip codes where USPS delays are most severe.

1. Ensure compliance with the Voting Rights Act — tribal communities in covered jurisdictions are entitled to language assistance. Verify that election materials and poll worker assistance are available in Lakota and Dakota languages where required.

1. Track SoS Johnson’s election security initiatives — ensure that any voter roll maintenance or security measures do not disproportionately affect tribal voters.
