Debates

Jackley and Noem participated in three debates.


First debate

In the first debate, both candidates tried to define the other. Jackley stated: "It’s Washington experience versus South Dakota experience." Noem said, "Marty’s background has been being a government lawyer."


Second debate

In the second debate, Noem discussed Jackley's scandals. "In EB5, the state oversight program, nobody went to jail. On Gear-Up, still, nobody's been punished. When we talk about what's been going on in Brookings with the Global Aquaponics scam—a con artist, Tobias Ritesman, held a fundraiser for Marty Jackley. Marty attended his phony groundbreaking for his phony project," Noem said. "People lost hundreds of thousands of dollars. Still, nobody's been investigated and nobody’s been prosecuted. That needs to change in our state." Jackley was on the defensive during the second debate. "Congresswoman, he didn’t hold a fundraiser for me. I was at an event that he was at, and I did go to a ground breaking because that's what important in South Dakota," Jackley says. "When we have businesses expanding I think it’s important that we attend those. You talk about Gear-Up, there hasn’t been a sentencing because these defendants are presumed innocent. But I as attorney general, unlike Washington, have done something about it. I actually formed a grand jury. Indictments have been issued. They're schedule to begin jury trials in July—or, excuse me—June, June 26th and I plan on trying those personally, because that’s what a leader does."


Final debate

In the final debate, Jackley and Noem took tough questions about workforce development, anti-discrimination laws, drugs, uniting Democrats and Republicans in the state to make critical decisions and much more. While they spent a lot of time talking about their plans for the state, they also spent a lot of time attacking each other's records. A major topic of contention was boards and commissions. The state currently has 134 of them. Noem said she wants to streamline different processes for licensure, eliminating "red tape" but Jackley disagreed. "Every time that a proposal comes forward to create a new 'blue ribbon' task force, a board or a commission, what typically comes with that is another layer of bureaucracy," Noem said. Jackley defended the government bureaucracy. "We need a governor that understands that various different boards, isn't out there criticizing different boards and saying that type of service isn't important," Jackley said. Jackley spoke about putting together a task force to work on government transparency and open records laws. "I'm committed when I become governor to put forth a taskforce ...because we need to take a look at the open records law," he said. Each candidate closed the debate with a final jab at the other. "It really comes to down to Washington experience versus South Dakota experience," Jackley said. "The congresswoman has been spending considerable time and effort talking about Marty Jackley, but I'm talking about you, South Dakota." "Days ago he stood up and talked about protecting victims while behind the scenes he was actively working to silence one to further his political career," Noem said. "You deserve a governor who will be honest with you, who will tell you the truth and who is willing to be accountable."

Constitution Party

Following an internal controversy within the Constitution Party of South Dakota over who was the legal party chair, Dan Lederman—individually and in his capacity as chair of the South Dakota Republican Party—sued Republican secretary of state Shantel Krebs to prevent her from certifying any Constitution Party nominees for the general-election ballot. For somewhat complex reasons, state circuit judge Patricia DeVaney ruled in favor of the Republican Party on August 17. G. Matt Johnson and Lora Hubbel—Constitution Party nominees for the state's at-large U.S. House seat and governor respectively—then sued Krebs in federal court on August 29, seeking ballot access for themselves and four other Constitution Party nominees. For various procedural reasons, federal district judge Roberto Lange ruled against the Constitution Party on October 1.
