South Dakota voters rejected a ballot question Tuesday that could have triggered a repeal of the state’s Medicaid expansion mandate. Some people who worked to defeat the measure said lawmakers should listen to voters and stop tinkering with the program.
The state’s Republican-dominated Legislature sent Amendment I to the ballot, where it failed with 56% of the votes against it and 44% in favor. Medicaid is a joint federal-state health insurance program for people with low incomes. In South Dakota, it traditionally covered specific low-income groups such as children, elderly people and disabled people.
In 2022, South Dakota voters approved expanding Medicaid eligibility to low-income adults with the federal government paying for 90% of the program and the state paying the remaining 10%. Amendment I would have repealed the expansion requirement if the federal government reduced its funding share.
Opponents of the amendment said voters have been clear on Medicaid expansion. “I think it shows that a majority of South Dakotans supported Medicaid expansion in the past and still do, and just don’t want to mess with it,” said Tim Rave, a Republican former legislator who’s now president and CEO of the South Dakota Association of Healthcare Organizations.
Rave said he isn’t sure if state lawmakers will ask voters again to consider changes to the program. In 2024, voters approved an amendment from lawmakers that authorized work requirements for Medicaid expansion recipients, predating a work requirement included in federal legislation approved the next year.
Rave said his focus now will be on the state’s revenues and how they could impact healthcare funding. Deb Fischer-Clemens, president of the South Dakota Nurses Association and a Democratic former legislator, led the opposition group No on I. She’s “hopeful that the message is clear and that we aren’t going to have to deal with this again.” “I just hope that they move on,” she said of lawmakers. “Other than that, we’ll be watching. We will be watching and paying attention and listening.” Her attention turns now to “the big picture,” she said, addressing Medicaid changes such as work requirements that came with President Donald Trump’s One Big Beautiful Bill Act.
The state Department of Social Services has estimated 1,213 people on expanded Medicaid, about 4% of the group, could be disenrolled after federal work requirements are implemented next year.
Rep. Will Mortenson, R-Fort Pierre, sponsored the resolution that sent Amendment I to the ballot. He said Tuesday that South Dakota’s schools and nursing homes, and the state’s balanced budget, could be imperiled if the state has to shoulder a bigger share of expanded Medicaid costs in the future. “I hope the Legislature keeps an eye on this issue going forward,” said Mortenson, who did not seek reelection this year.

That worries state Sen. Taffy Howard, R-Rapid City, who won her bid for reelection Tuesday and sits on the state’s budget committee. She said “something has to be done” about the potential budget constraints that would come with reduc
