What’s at stake
Deep-red South Dakota has an open House seat this year after incumbent Rep. Johnson (R) vacated to run for governor (though he lost his primary). In a cycle where Democrats are vying for Congress, the Mount Rushmore state likely isn’t on their pickup list. Every SD race is heavily favored toward Republicans. South Dakotan voters are feeling the effects of inflation, along with the rest of the country. In a 2026 poll, 35% ranked it as the top issue facing the state, followed by threats to democracy (13%), housing affordability (13%), education (11%), and healthcare (9%).

All U.S. House of Representatives seats are up for election every two years. Find your district here.
- Shadrach’s big picture
South Dakotans will elect one representative to send to Congress. A Republican has held that seat since 2011.
- Open seats
Yes, SD’s one seat is open. Rep. Dusty Johnson (R) ran for governor.
- Competitive districts
South Dakota’s one at-large district is considered solidly Republican. The deep-red state is almost guaranteed to re-elect a Republican, though candidates in both parties filed to run, so the seat isn’t guaranteed to the GOP.

South Dakota voters put Medicaid expansion in the state constitution in 2022. The federal government currently covers 90% of the cost. This amendment would let the state end expanded coverage if that federal share ever dropped below 90%. If that happened, Medicaid would go back to covering only its traditional groups: low-income children, pregnant women, people with disabilities, and the elderly. Roughly 30,000 South Dakotans are covered under the expansion.

Non-citizens already cannot vote in South Dakota elections; this spells out the disqualification.

Non-citizens still could not vote in South Dakota electionsThe state holds on to money people have forgotten about: uncashed checks, dormant bank accounts, unclaimed insurance payouts. Right now, much of that money flows into general state spending. This amendment would move it into a protected trust fund instead: the original money stays available for rightful owners to claim, and the state could spend only the interest it earns.

This amendment would raise that bar to 60% for all future amendments, whether proposed by the legislature or by a citizen petition. The new 60% threshold would not apply to initiated laws, only constitutional amendments, and Amendment L itself needs only a simple majority to pass. Supporters say the constitution should be harder to change. Opponents say it weakens the citizen initiative process, which South Dakota was the first state to adopt in 1898.

A prayer for South Dakota
Maker of prairies and plains, guard South Dakota from the unrest that so easily permeates election season. As South Dakotans approach this time of great decision, help voters rightly balance the weight of responsibility, knowing it is a privilege to steward, but not a power that can irreparably harm Your good purposes.
Grant South Dakotans wisdom and discernment in the ballot box to elect leaders who govern in love, seek the flourishing of their people, and enact policies that promote justice.
The Mount Rushmore State’s leaders are streams of water in Your hand, O Lord; You direct them as You will. As we wait for Your kingdom in a loop of lesser kings, through seasons of change and uncertainty, teach us not to fear. The fate of our world does not hang in the balance, for our King has come, and He will come again soon.
Amen.
