• Ten Republicans who lost their seats in the Legislature in 2024 are trying to win them back this year.
• Incumbents and lawmakers who gave up House seats to run for Senate fell to challengers in several places.
• Votes are still being tallied across the state.

The makeup of the Legislature was up in the air as of 1 a.m. after South Dakota’s primary election. 

Ten Republican state lawmakers ousted in 2024 are angling to get their seats back in 2026. Results were mixed for the nine who had primaries on Tuesday, with results still coming in for several races and others set for possible recounts.

Shawn Bordeaux of Rosebud won the state’s only Democratic primary, beating Troy “Luke” Lunderman for a chance to return to the state Senate.

Bordeaux will face Chamberlain Republican Rebecca Reimer in November’s general election. Reimer, who was term-limited in the state House of Representatives, beat Lower Brule Sen. Tamara Grove in Tuesday’s primary.

WATERTOWN: Recounts possible after tight Codington County vote in primary

In Watertown’s District 5, Rep. Josephine Garcia fell in a state Senate primary to incumbent Sen. Glen Vilhauer. Garcia beat Byron Callies in the 2024 primary to earn her seat in the House of Representatives, but opted to challenge Vilhauer for his Senate seat instead of seeking reelection to the House. 

Callies, Vilhauer and Garcia are all from Watertown.

Vilhauer won with 59% of the vote. His was one of the first state legislative victories of the night reported on the Secretary of State’s website.

Vilhauer won handily, but he said he wasn’t necessarily expecting to as polls opened on Tuesday.

“I knew it was going to be a battle going in,” Vilhauer said. “She worked hard on her side, and I didn’t know what to expect.”

Callies was among the first to call Vilhauer to congratulate him, around 9:30 p.m.

“I’m happy, because Glen’s a solid legislator,” said Callies, who’s angling to win his seat back in the general election.

Garcia did not return a call seeking comment.

GOVERNOR: Toby Doeden forces runoff against Gov. Larry Rhoden

In District 21, Sen. Mykala Voita of Bonesteel beat former Sen. Erin Tobin of Winner in a rematch of their 2024 contest, which Voita won by a few dozen votes that year. This time around, Voita bested Tobin by 1,002 votes. 

In response to a request for comment, Voita sent a text reading “Glory to God!”

Tobin did not return a call from South Dakota Searchlight about her race after it was called, but said earlier in the evening she would be “at peace” with the results regardless of what they might be.

Another rematch saw Yanktonites Lauren Nelson and Jean Hunhoff battling for District 18’s state Senate seat. Nelson was a newcomer in 2024 when she beat Hunhoff, who’d spent decades in the Capitol between stints in the House and Senate. On Tuesday, Nelson held off Hunhoff, winning by 243 votes.

Other notable races

Gov. Larry Rhoden, who replaced Kristi Noem last year when President Donald Trump nominated her to lead the Department of Homeland Security, was battling with Rep. Dusty Johnson and former state House Speaker Jon Hansen for a second spot in the July 28 runoff. The primary will go to a runoff because no candidate eclipsed 35% of the vote.

Trump did not issue an endorsement in the race. Doeden branded himself on his campaign website as “a total political outsider who’s tired of the government’s failure to deliver on its promises” and one of Trump’s “fiercest supporters.”

Rhoden, a former lieutenant governor, agriculture secretary and lawmaker, campaigned on property tax cuts and lowering crime in his bid for a four-year term.

Johnson is the state’s lone representative in the House, where he previously was chair of the Republican Main Street Caucus. Hansen, who was elected to the South Dakota House in 2010, held several leadership positions before he became speaker.

The Republican nominee will be the favorite to win the general election in the solidly red state this fall. A Democrat has not served as governor in South Dakota since the 1970s, and Trump carried the state by 29 points in 2024.

Agronomist: eastern South Dakota crops hit and miss

An agronomist in eastern South Dakota says corn and soybeans are hit and miss as the growing season begins.

Steven Zemlicka with AgTegra Cooperative tells Brownfield, “We’ve got corn anywhere from V1 all the way up to V4. Biggest stuff’s maybe touching V5. Corn’s coming right along, looks pretty good. A little bit of hail here too, but I don’t think it’s going to be much of an issue. Stands for the most part are pretty good, pretty solid.”

Zemlicka says soybean emergence has been slow due to the wet, cool conditions, and there are a few fields that still need planted.

“People were still working on planting soybeans when we got the recent rain.”

He says recent rain totals ranged from a half inch to as much as four inches in the northeast part of South Dakota; the southern part of the state has been drier.

South Dakota’s corn is rated 61 percent good to excellent, with soybean conditions rated 57 percent good to excellent, according to USDA’s first condition ratings of the season.
