Where the road gets harder
Every rule is a cost, and it doesn't fall on everyone the same. A deadline, a document or a trip to an office is easy for some people and a real obstacle for others: people who work hourly jobs, move often, live far from an office, don't drive, or have a disability. Here is what that looks like in South Dakota.
- Registration closes before Election Day (in person: Monday, October 19). Miss it and you can't vote in this election. If you've moved, your registration may need updating by then too.
- Registration isn't automatic. Each person has to sign up on their own, which leaves out people who don't know the rules or move often.
- There's no online registration. Signing up means a paper form by mail or a trip to an office.
- A 2026 law (SB 175) requires documentary proof of citizenship to vote in state races.
- Mail ballots have to arrive by Election Day; a postmark isn't enough. A ballot mailed in the last days can arrive too late and won't count, so return it in person if it's close.
- After a felony conviction: Rights restored automatically after completing the sentence including parole/probation.
- The Sentencing Project estimated in 2024 that 12,603 people in South Dakota (1.92% of the voting-eligible population, and 10.78% of Black voting-eligible residents) could not vote because of a felony conviction.Source: The Sentencing Project, Locked Out 2024
