Iowa GOP Primary Tests Kansas-Tied Gubernatorial Candidate Zach Lahn’s ‘Iowa First’ Pitch
Why It Matters
Iowa voters head to the polls Tuesday in a Republican gubernatorial primary that includes an unusual candidate: a businessman and private school co-founder with deep roots in Kansas, raising questions about residency, authenticity, and the changing nature of state-level political campaigns.
What Happened
Zach Lahn, who co-founded a Wichita private school in 2018 and voted in Kansas elections as recently as 2022, is mounting an insurgent campaign for governor of Iowa under an “Iowa First” banner. He transferred his voter registration to Iowa in October 2024 — the move that satisfied the state’s two-year residency requirement for the 2026 race.
Lahn grew up near Sioux City, Iowa, and attended the University of Colorado before working for members of Congress in Montana and Colorado and serving as Montana director of Americans for Prosperity. He later moved to Wichita, where he co-founded a pre-kindergarten through 12th-grade school called Wonder on the campus of Wichita State University, financed in part by Chase Koch, son of billionaire Charles Koch.
Lahn’s current wife, Annie, was previously married to Chase Koch. The couple has seven children in a blended family and has featured them prominently in campaign materials.
His platform opposes abortion and high taxes while defending gun rights, school vouchers, and religious freedom. He has positioned himself as an anti-establishment populist, criticizing what he calls a “Uni-party” in which both Republicans and Democrats serve entrenched special interests rather than voters.
On Tuesday’s primary ballot, Lahn faces U.S. Rep. Randy Feenstra, state Rep. Eddie Andrews, former state Rep. Brad Sherman, and former Iowa Department of Administrative Services director Adam Steen. The general election Democratic nominee is Iowa state Auditor Rob Sand, who ran unopposed in his primary.
By the Numbers
- $2 million — the amount Lahn loaned his own campaign, funding a heavy television advertising presence across Iowa
- 2018, 2020, 2022 — the Kansas election cycles in which Lahn cast ballots, including a provisional ballot in Sedgwick County in 2018 and an advance ballot in the August 2022 primary
- October 17, 2024 — date Lahn registered to vote in Iowa, meeting the two-year residency threshold for the 2026 governor’s race
- 37 flights — the number of times Lahn reportedly flew from Iowa to Wichita in his personal aircraft between October 2025 and April 2026, which he attributed to visiting children from prior marriages
- $1 — the price at which the Lahns sold an Iowa-area home to an LLC after Annie Lahn had declared it her primary residence on mortgage documents roughly a year earlier
Residency Questions and Property Transactions
Iowa Democrats have raised the residency issue publicly, pointing to Lahn’s extended presence in Kansas and the timing of his voter registration transfer. In July 2024, Annie Lahn purchased a home near Wichita and listed it as her primary residence on mortgage documents. Less than two weeks after the couple sold that property to an LLC for $1 in July 2025, she registered to vote in Belle Plaine, Iowa — where Lahn had previously owned farmland since 2014.
Lahn’s campaign did not respond to questions about his Kansas ties or why he chose Iowa rather than Kansas for his gubernatorial run.
Zoom Out
Iowa’s race is unfolding without an incumbent on the ballot for the first time since 2006. Republican Gov. Kim Reynolds, who carried some of the lowest approval ratings among sitting governors nationally, did not seek reelection.
Political scientists note that the Trump era has loosened traditional expectations around gubernatorial candidates. As national political dynamics shift, candidates without deep local roots or prior office experience have found openings previously unavailable to them. Michael Smith, a political science professor at Emporia State University, said Lahn “is trying to be his own kind of populist” — a profile that would have been harder to sustain in an earlier political environment.
Still, Drake University journalism and political communication professor Jennifer Konfrst cautioned that Iowa voters scrutinize whether a candidate’s biography and network are authentically local. “Being from here matters,” she said. “It’s not unimportant that somebody who wants to be governor of Iowa isn’t from here.”
What’s Next
Tuesday’s primary will determine whether Lahn’s self-funded campaign and anti-establishment message can overcome doubts about his Kansas connections. If he advances, he would face Democratic nominee Rob Sand in the general election — a contest that will also serve as an early indicator of how competitive Iowa’s governor’s race becomes in 2026.
