A four-way fracture in the South Dakota Republican gubernatorial primary has shattered the illusion of a unified conservative establishment, forcing the state toward an unprecedented summer runoff election. Initial returns from the June 2 vote reveal that no candidate came close to the 35% threshold required to secure the nomination outright. Instead, political newcomer Toby Doeden leads the pack with roughly 30% of the vote, closely pursued by incumbent Governor Larry Rhoden at 26%, U.S. Representative Dusty Johnson at 24%, and state House Speaker Jon Hansen at 21%.
This statistical deadlock is not just a competitive race. It is an open ideological civil war over who owns the mantle of modern conservatism in a state where winning the Republican primary is historically equivalent to winning the office.

The Myth of the Incumbency Advantage
South Dakota politics operates under a unique pressure cooker. When former Governor Kristi Noem resigned in early 2025 to take the helm of the Department of Homeland Security, Larry Rhoden inherited the executive mansion. Historically, an incumbent governor in Pierre enjoys an almost unassailable path to a full term. Rhoden, a rancher who served as Noem’s loyal lieutenant governor since 2019, assumed the transition would be seamless.
It was not. Serving the remainder of Noem's term did not grant Rhoden the institutional shield usually afforded to an incumbent. The electorate did not view him as an established leader, but rather as a placeholder. As discussed in detailed reports by BBC News, the implications are widespread.

*35% required to avoid a July 28 runoff
Rhoden’s inability to clear the field invited a dangerous internal challenge. His campaign relied heavily on the legacy of the Noem administration, emphasizing agricultural roots and institutional continuity. However, the data proves that relying on past administrative momentum is a failing strategy when the grassroots base demands active, disruptive populism.
The Populist Insurgency of Toby Doeden
The real shockwave of the primary belongs to Toby Doeden, a retail and real estate executive who entered the race as an outsider and walked away with the pole position entering the July 28 runoff. Doeden systematically dismantled his opponents by running on a singular, hyper-focused message: the absolute elimination of property taxes.
While career politicians debated fiscal nuances, Doeden capitalized on local anxieties regarding rising inflation and stagnant wages. His platform treated property taxes not just as a policy issue, but as an existential threat to generational farm ownership and working-class housing stability.
By positioning himself as an anti-corporate outsider, Doeden tapped into a vein of populist anger that has simmered in the rural West for a decade. He successfully painted both Rhoden and Representative Dusty Johnson as creatures of the political establishment who are too comfortable with corporate welfare and state spending.
The Conundrum of the Governing Conservative
Dusty Johnson enters the runoff preparation facing a structural ceiling within his own party. As South Dakota’s sole U.S. Representative since 2019, Johnson boasts massive name recognition and a formidable campaign war chest. He secured high-profile endorsements, including former Governor Dennis Daugaard, representing the traditional, business-friendly wing of the South Dakota GOP.
Yet, Johnson's pragmatic, governing-style conservatism failed to ignite the enthusiasm of the modern primary voter. In Washington, Johnson built a reputation as an effective legislator who focuses on policy mechanics rather than cultural warfare. In a general election, that profile makes him immensely formidable. In a closed Republican primary, where independents are locked out, it acts as a liability.
The primary numbers suggest that Johnson’s coalition of urban professionals in Sioux Falls and traditional institutionalists is insufficient against a divided field of hardline populists. His campaign must now figure out how to peel away voters who backed Speaker Jon Hansen's ideological platform without alienating his moderate base.
Localized Friction Over Corporate Power and Land Rights
To view this primary strictly through the lens of national political alignments is a mistake. The underlying current driving South Dakota voters is deeply rooted in local economic friction, specifically concerning eminent domain and agricultural property rights.
For several legislative sessions, a fierce battle has raged in Pierre over carbon capture pipelines and the extent to which private corporations can use eminent domain to seize agricultural land. This issue does not split neatly along traditional liberal or conservative lines. It pits property-rights purists against industrial agricultural interests and corporate developers.
- Jon Hansen and Toby Doeden aligned themselves aggressively with the property-rights faction, capturing the loyalty of rural landowners who feel abandoned by the state capital.
- Larry Rhoden faced intense scrutiny for trying to strike a balance, which critics framed as a capitulation to corporate lobbyists.
This localized anger explains why an outsider like Doeden can outperform a sitting governor and a sitting congressman. The rural base believes the political class has prioritized corporate advancement over foundational land ownership rights.
The Runoff Mechanics and the Missing Endorsement
The race now pivots to a high-stakes, two-candidate sprint leading to the July 28 runoff election. The strategic calculus for both surviving campaigns will rely entirely on where the supporters of the eliminated candidates migrate.
Jon Hansen’s 21% share of the vote represents the ideological anchor of the state legislature. As Speaker of the House, Hansen commanded the respect of the party’s most disciplined conservative activists. Logic suggests that his voters, driven by a desire for constitutional purism and property rights protection, will naturally gravitate toward Doeden rather than the institutionalist options.
Hovering over this entire landscape is a glaring omission: Donald Trump chose not to endorse a candidate in this primary. While the former president issued clear endorsements for Mike Rounds in the U.S. Senate race and Marty Jackley for the U.S. House seat, he left the gubernatorial field completely open.
Without a decisive signal from Mar-a-Lago, the candidates were forced to litigate the definition of true conservatism on their own merits. The results show a party deeply divided between the governing pragmatism of the past and the disruptive populism of the present. The upcoming runoff will not just select a nominee; it will dictate the structural direction of South Dakota’s political economy for the next decade.
