New landscape confronts South Dakota Republicans after political earthquake shakes incumbents • South Dakota Searchlight
A literal 3.7-magnitude earthquake shook the state Capitol in Pierre last week. State Rep. Scott Odenbach, R-Spearfish, said a political earthquake shook the Capitol on Tuesday night.
“The people are waking up,” Odenbach said.
He and others within a faction of the South Dakota Republican Party say it’s being run by politicians who are not as conservative as the party’s base of supporters. Their efforts to change that contributed to 14 losses by incumbent Republican legislators in Tuesday’s primary election. Odenbach’s political action committee spent $58,000 ahead of the primary in support of some winning candidates.
Current Republican House Majority Leader Will Mortenson, R-Fort Pierre — who is unopposed for reelection — said new legislators are always welcome, but losing 14 incumbents comes with a cost.
“It’s an opportunity for new ideas, but it does mean we lost a lot of institutional knowledge,” he said.
Those losses include Sen. Jean Hunhoff, R-Yankton, who’s served 24 years in the Legislature, and Sen. Ryan Maher, R-Isabel, who has served 16 years, among others.
Mortenson’s political action committee spent $48,271 to help some of the incumbents and other candidates that Odenbach opposed.
Mortenson blamed the incumbent losses mostly on historically low voter turnout of 17%, which he said creates an environment in which a motivated faction can turn out enough voters to swing a primary race.
Pipelines and property taxes
Odenbach said challengers won because of quality candidate recruitment, a good ground game and the right messaging.
Much of that messaging, especially in eastern South Dakota, capitalized on opposition to Summit Carbon Solutions’ proposed multibillion-dollar pipeline project. It would collect carbon dioxide produced by ethanol plants in South Dakota and other states and move it through an underground pipeline for sequestration in North Dakota, passing through farms, ranches and other private property along the way.
Incumbent Republican legislators suffer losses as pipelines and property rights surge to the fore
The project has caused more than two years of legal and legislative wrangling over landowner rights and eminent domain, the legal maneuver through which a company can seize property for projects in the public interest.
“A lot of candidates have been saying South Dakota is open for business, but not for sale, and that was proven last night,” Odenbach said.
Mortenson and some other Republican leaders passed a bill during the last legislative session to preserve a regulatory path forward for the pipeline while ensuring landowners receive additional protections. That put them at odds with some in their own party who sought stricter measures such as a ban on eminent domain for carbon pipelines. Some members of that faction are gathering petition signatures to refer the bill passed last session to a public vote in November.
Odenbach said the pipeline debate is not over.
“We’re going to be back next session to better define public use and who gets to use eminent domain in South Dakota, like I tried to do during the recent session,” he said.
Incumbent Rep. Aaron Aylward, R-Harrisburg, won his primary. He’s the president of the South Dakota Freedom Caucus, which has butted heads with Republican leadership. On the topic of pipelines, he said, “It’s not looking good for the carbon ones, that’s for sure.”
Aylward said incumbents lost Tuesday because “people are tired of the same type of bureaucratic garbage they’ve been fed for the last number of years.”
Meanwhile, in the Black Hills, rising property taxes animated many Republican voters. Former legislator Tim Goodwin, of Rapid City, earned one of District 30’s two Republican House nominations Tuesday. He and incumbent Rep. Trish Ladner, of Hot Springs, will face one Democrat in the November race for two House seats.
“Out here, property rights isn’t even on the radar,” Goodwin said. “It’s property taxes.”
Greasing the open primaries wheel
Some Republicans think the inner-party friction is self-defeating. Pat Powers, writer of the Dakota War College political blog, said Tuesday’s primary results offer Democrats an opportunity to win some general election races if they run to the middle of the political spectrum. Democrats currently hold only 11 of the Legislature’s 105 seats.
“It could very well mark a shift in the Republican party’s fortunes,” Powers said.
Powers said Republican infighting also gives an open primaries ballot measure a better chance of passing during the November general election. The measure would change some primaries to include all the candidates for an office, rather than splitting the candidates into party-specific primaries.
Tuesday’s low turnout and poor showing by incumbents gives ammunition to open primaries supporters, Powers said.
“They can say, ‘Look at what happens when we don’t have open primaries,’ and they have the money to get the message across.”

Drey Samuelson, who worked as Democratic former U.S. Sen. Tim Johnson’s chief of staff for many years, is involved in the open primaries effort. He’s already making that argument.
“The closed primary system does not work very well. It nominates people who are to the extremes of the parties,” Samuelson said. “We can look at these primary results to see that.”
Samuelson said turnout would have been better if Democrats and independents had more to vote on than the Democratic presidential primary, in which President Joe Biden was already all but guaranteed a victory. There was only one Democratic legislative primary Tuesday in South Dakota, and 44 Republican legislative primaries.
Seeking change ‘for the average person’
Joy Hohn, a vocal opponent of eminent domain for carbon dioxide pipelines, bested former legislator Mark Willadsen for the Republican nomination for Sioux Falls District 9’s Senate seat. There is no Democratic or independent candidate running in the general election.
Hohn received a donation from Odenbach’s political action committee.
“I think that the citizens of South Dakota are seeing the need for a bigger focus on ‘we the people,’” Hohn said. “We don’t really need this pipeline.”
Hohn said the results of the election move the state in the right direction, “toward true conservative values and our country’s founding principles.”
Republican factions fighting for control of the party in Tuesday’s primary election
Incumbent Sen. Erin Tobin, R-Winner, fell by 48 votes (which is within the possible recount margin) to a political newcomer from Bonesteel named Mykala Voita, who also campaigned on the primacy of landowner rights.
“The people of South Dakota drew a line and they are speaking,” Voita said. “I think the people are sending a clear message that we don’t want to be trampled on, and if they’re going to come into our state, they’re going to play by our rules.”
In a four-way District 13 House of Representatives primary, incumbent Republican Tony Venhuizen, of Sioux Falls, advanced to the general election as one of the top two finishers. But he received fewer votes than newcomer John Hughes. There is no Democrat or independent on the ballot in November.
Hughes plans to push for change.
“Government just isn’t working for the average person in South Dakota, especially in terms of economic development,” Hughes said. “It’s helping large corporate interests that are not paying their fair share when they come into South Dakota and take advantage of our business climate, and it’s at the expense of the taxpayer.”

Black Hills Bottlenecks: Road work update for the week of May 11
RAPID CITY, S.D. (KOTA) – More road work and travel impacts are set to begin across western South Dakota this week, with projects ranging from highway striping and crack sealing to temporary rest area closures as well as an upcoming public meeting on a bridge replacement project in Keystone.
The first projects begin Monday, May 11.
S.D. Highway 44: Striping work
On S.D. Highway 44, crews will complete striping work from about 1.5 miles east of Farmingdale to roughly 10.75 miles east of the community.
Work is scheduled from 6 a.m. to 5 p.m. Monday and is expected to continue through Tuesday evening. Drivers should expect daytime lane impacts in the area.
U.S. Highway 385: Striping work
Also beginning Monday, striping operations are scheduled on U.S. Highway 385 from about one mile south of the U.S. Highway 85 junction near Deadwood to the junction itself. Work is expected to take place during daytime hours Monday through Tuesday.
Pavement preservation project on S.D. Highway 20
A pavement preservation project is also scheduled to start Monday on S.D. Highway 20 between Buffalo and Camp Crook. Crews will be sealing cracks in the roadway as part of the project. Traffic will be reduced to one lane during daytime hours, with flaggers and a pilot car guiding motorists through the work zone. Delays of up to 15 minutes are expected.
The contractor for the $112,155 project is Highway Improvement, Inc. of Sioux Falls. The overall completion date is scheduled for Dec. 4.
Drivers are reminded to slow down and use caution around crews and construction equipment in all work zones.
Wasta rest area spring cleaning
Additional travel impacts are expected latter this week with temporary closures planned at the Wasta Rest Areas along Interstate 90 for annual spring cleaning.
The eastbound Wasta Rest Area near mile marker 98 will close at 7 a.m. Tuesday, May 12, and reopen at 9 a.m. Wednesday, May 13. After that reopening, the westbound rest area will close from 9 a.m. Wednesday until 9 a.m. Thursday, May 14. Travelers are encouraged to make alternate plans during the closures.
Public meeting on future bridge replacement project along U.S. Highway 16A in Keystone
On Thursday, May 14, the South Dakota Department of Transportation and Complete Concrete, Inc. will host a public informational meeting on a future bridge replacement project along U.S. Highway 16A in Keystone.
The open house-style meeting will run from 4:30 p.m. to 6:30 p.m. at the Keystone Community Center, 1101 Madill St. Officials say the meeting is intended to provide project details and answer questions from residents, businesses and emergency personnel.

The bridge replacement project is scheduled to begin in October. Plans call for replacing the existing bridge with a box culvert and include additional improvements such as intersection upgrades, resurfacing, pavement markings, traffic signals, ADA upgrades and erosion control. Pedestrian access on both sides of the structure will also be improved.
More information on the Keystone project is available at South Dakota Department of Transportation’s project page.
Current road conditions, closures and construction updates can be found at SD511 or by dialing 511.

After Standing Rock, could a canceled mine project offer a roadmap for opponents of a new oil pipeline in South Dakota?
Almost exactly a decade since the start of the Standing Rock protests against the Dakota Access pipeline gained national and international attention, new disputes are simmering over tribal rights in the Black Hills of South Dakota.
Earlier this month, an environmental organization and a Native American advocacy group sued the US Forest Service, claiming that an exploratory graphite drilling project on national forest land threatened a recognized ceremonial site on mountain meadows known as Pe’ Sla, or Reynolds Prairie.
But on Friday, Pete Lien and Sons, the company behind the project, abruptly withdrew, saying it would perform reclamation on the site and would not seek to file another plan. The decision came as a striking victory for Native American tribes and environmental groups that had opposed it – but other projects in the works may not meet the same conclusion.
The project, claimed nine groups within the Sioux Nation, including the Standing Rock Sioux, would “directly and significantly” affect the use of Pe’ Sla, which sits within Ȟe Sápa, the Lakota name for the sacred Black Hills of South Dakota, itself the locus of Lakota creation myths.
A second exploratory project by a Canadian company looking to mine uranium on state-owned land could affect Craven Canyon, an area that contains 7,000-year-old sites of importance to Indigenous tribes, historians and archaeologists.
Opposition to the twin projects – backed by Pete Lien, of Rapid City, and by Clean Nuclear Energy Corp – comes as a proposed Alberta-to-Wyoming pipeline for carrying Canadian crude oil to the US is close to securing commitments from oil companies after Donald Trump granted permitting through an executive order.
All the projects have at their heart issues of extraction, water safety and sacred sites, much as the Standing Rock dispute of 2016 that saw “water protesters” gather in a standoff with law enforcement over concerns regarding water safety and sacred sites.
That case began when the Standing Rock Sioux passed a resolution stating that “the Dakota Access Pipeline poses a serious risk to the very survival of our Tribe and … would destroy valuable cultural resources” and was a violation of the 1868 Fort Laramie Treaty guaranteeing the “undisturbed use and occupation” of reservation lands surrounding the pipeline.
In the aftermath, the environmental group Greenpeace was ordered to pay damages of $345m by a North Dakota judge to pipeline company Energy Transfer and subsidiary Dakota Access in connection with the protests, an order that is set to go to appeal. Greenpeace claims the legal action is designed to silence activists.
Most of the current disputes relate to energy, reflecting the Trump administration’s drive toward US energy independence and away from dependence on foreign sources, particularly China. Graphite, used in electric vehicle batteries, is almost exclusively imported. Roughly 95%–99% of uranium is purchased from foreign sources, including Russia and Kazakhstan.
The pipeline deal, meanwhile, is expected to help increase oil output from Canada, the world’s fourth-largest producer, to around 6.1m barrels a day, up from 5.5m now. Bridger, the company behind the Alberta-to-Wyoming pipeline, has said the project was being developed in response to identified market interest.
Wizipan “Little Elk” Garriott, a member of NDN Collective, an Indigenous rights group opposing the mining at Pe’ Sla, says the entire process of approval for the planned mine “happened in the dark”.
“There was no notice that they were proceeding provided to us, nor to the sovereign tribal nations,” he says, in violation of environmental and cultural impact study requirements and consultations with the tribes.
Lilias Jarding, director of the Black Hills Clean Water Alliance, one of the parties in the victorious Pe’ Sla action, says the decade since Standing Rock has seen a huge growth in projects attempting to mine tribal lands and areas of ceremonial significance.
Since the start of the second Trump administration, the push for both minerals extraction and energy has dramatically increased. “They’re being more aggressive,” Jarding says. In the case of Pe’ Sla, he adds, the company didn’t stop drilling when the lawsuits was filed: “They started drilling 24 hours a day.”
The alliance, along with tribes, claim the graphite project violated the National Environmental Policy Act (NEPA) and the National Historic Preservation Act (NHPA) and that the US Forest Service improperly used a process known as a “categorical exclusion” to bypass reviews.
Oglala Sioux president Frank Star Comes Out said in a statement that the Sioux tribes never ceded to the US the lands in the Black Hills, which, he said, “remain the spiritual center of the Great Sioux Nation and they are not for sale, lease or exploitation” and that the lawsuit is a “united tribal response to protect a sacred site from those who continue to desecrate our ancestral lands”.
Oglala activist Taylor Gunhammer said that drilling at Pe’ Sla was akin to “drilling under the Vatican or at a sacred site in Jerusalem”.
A representative of Clean Nuclear Energy Corp, Mike Blady, said the company was “aware of the cultural significance and are doing everything in our power to ensure that there is no collateral damage”.
Will this amount to a populist action similar to Standing Rock?
The Pe’ Sla dispute did not provoke the kind of Indigenous-led, grassroots resistance to fossil-fuel infrastructure projects that accompanied the Dakota Access pipeline, which in some ways became a template for contemporary protests, powered by social media, celebrities and politicians.
The tribes were not in favor of following in that direction, Jarding says: “It’s a deeply sacred spiritual and ceremonial site, and elders have made it clear that it’s not a good place for another Standing Rock with thousands of people. They say this is not the place.”
Under the Biden administration, the tribal groups felt they were entering into a period of co-management policy over federal lands that in many cases lie within treaty agreements. But under the Trump administration, that sense of co-operation has diminished.
“We’ve seen a ramp-up of opening up federal lands for mineral and gas exploration, but as a planet we need to be moving away from fossil fuels and toward policies that are sustainable into the future,” says NDN’s Garriott.
What was planned for Pe’ Sla now, or was happening at Standing Rock a decade ago, or has indeed happened over a long history of disputes between sovereign tribal groups and the US government, he says, is “protecting our land and protecting our water, not only for ourselves but for the planet. We’re not random protesters out there – we’re protecting our own land”.
