Direct Democracy in South Dakota: A Voter's Guide to Ballot Measures

When most people think about voting in South Dakota, they picture candidate races — governor, senator, state legislator. But on nearly every ballot, South Dakotans are also asked to weigh in on something different: policy questions they get to decide directly, without a politician in the middle.

These are called ballot measures, and they're one of the most powerful tools voters have to shape the laws that govern their lives — even when their elected representatives won't act. If you're new to the concept, these two guides cover the basics: What is direct democracy and why does it matter? and How ballot measures, initiatives, and referendums work. This article focuses specifically on how that process plays out in South Dakota, what voters here have accomplished with it, and what's at stake for it in 2026.

How Do Ballot Measures Work in South Dakota?

South Dakota allows two types of ballot measures:

Citizen-initiated measures. South Dakota voters can draft a proposed law or constitutional amendment themselves and gather signatures from fellow registered voters to put it on the ballot. If enough valid signatures are collected and certified by the required deadline, the measure appears on the ballot in an upcoming election. Citizens frequently use this process when the state legislature has refused to act on a policy that has broad public support.

Legislatively-referred measures. The South Dakota Legislature — made up of the South Dakota Senate and the South Dakota House — can also vote to send a policy question directly to voters. These are common when lawmakers want to change the state constitution or when they want voters to weigh in on a major policy question.

Both processes put the final decision in voters' hands.

How Have South Dakotans Used Ballot Measures?

South Dakota voters have used ballot measures to make meaningful policy changes, often on issues where the state legislature was unwilling to act. In recent years:

• South Dakota voters rejected a legislative proposal to enact minority rule for some ballot measures.
• South Dakota voters approved a ballot measure to legalize the use of medical marijuana.
• South Dakotans approved a ballot measure to raise the minimum wage, giving workers a pay increase the legislature had not passed on its own.
• South Dakota voters approved a ballot measure to expand Medicaid, extending health coverage to tens of thousands of residents, a policy that had stalled in the legislature for years.

Ballot measures can be used by Democrats, Republicans, third-party voters, and independents alike. No single part of the political spectrum controls the process, and often, coalitions that cross party lines are on the same side of a ballot question. Ballot measures are often popular with voters across the political spectrum.

What Are the Benefits of Direct Democracy for South Dakota Voters?

Direct democracy gives South Dakota voters the ability to make law themselves. It cuts through partisan gridlock by removing party labels from policy questions. It creates durable, voter-approved policy wins. And it gives residents a direct voice on issues that deeply affect their daily lives.
