Iowa's Governor Race Just Got Interesting. Here's What Kalshi Thinks.

April 12, 2026 · By Tyler Jacobsma

Kalshi has Iowa's GOP governor primary at Feenstra 69%, Steen 16%, Lahn 16%. Cook just moved the general to tossup. Here's why the primary suddenly matters — and what's making Feenstra's lead drift.

Iowa's primary is June 2. The general election is November 3.

THE KALSHI BOARD: FEENSTRA IS THE FAVORITE. THE QUESTION IS WHETHER HE SHOULD BE.

Kim Reynolds is retiring. Five Republicans want to replace her. Here's where the money sits:

Source: Kalshi — "Iowa Republican Governor nominee?" $49.6K volume. Begins June 2.

Randy Feenstra: 69% Adam Steen: 16% Zach Lahn: 16%

Feenstra has been the presumptive frontrunner since he entered the race. He's the congressman from Iowa's 4th District. He's got $4.3 million in cash on hand — more than every other Republican combined. He has Terry Branstad's endorsement (the longest-serving governor in American history). He rode on Air Force One with Trump during the president's Iowa trip and is actively seeking Trump's endorsement.

At 69%, Kalshi says he's the heavy favorite. But look at that chart. His line has been drifting down since February, when he was near 80%. Meanwhile, both Steen and Lahn have been climbing. Something is moving under the surface.

Three reasons the market is tightening.

Feenstra won't debate.

He's skipped every forum and debate so far, including the Moms for Liberty event last month where four other candidates showed up. In a primary where name recognition matters, ducking debates looks like you're hiding from your own base. Steen has gone after him hard on this, telling crowds: "If Feenstra's the candidate, Rob Sand's your next governor and we are toast as a state." That line got cheers.

Steen has The Family Leader.

Bob Vander Plaats — the kingmaker of Iowa's Christian conservative base — endorsed Steen personally. Then The Family Leader's board unanimously backed him with their full political organizing and financial support. In a state where evangelical voters are a massive chunk of the GOP primary electorate, this endorsement matters more than Branstad's. Vander Plaats also made a pointed argument: Iowa has never elected a congressman as governor. He named three who tried and lost.

Lahn has the MAHA lane and his own money.

Lahn is the outsider play. He's a farmer and businessman from Belle Plaine who put $2 million of his own money into the campaign and raised another $400K in a single month. He's aligned with RFK Jr.'s "Make America Healthy Again" agenda, talking about Iowa's cancer rates, water quality, and the influence of big ag and big pharma. The MAHA PAC endorsed him. In a state where people are increasingly worried about what's in their water and food, this message has an audience.

WHY THE PRIMARY MATTERS MORE THAN USUAL

Cook Political Report just moved this race to "tossup." That changes everything about the primary calculation.

Rob Sand is the real threat. The Democratic state auditor has been quietly building a statewide operation that looks nothing like a typical Iowa Democrat's campaign. He submitted nearly 25,000 petition signatures — breaking the state record. More than one-fifth of those signatures came from no-party voters and Republicans. He's outraised every Republican candidate. And he's been running a "not redder or bluer, but better and truer" message that's designed to peel off moderate Republicans.

Electability is now the primary question. If Republicans nominate someone who can't beat Sand, they lose the governor's mansion for the first time in 20 years. This is where Feenstra's 69% starts looking fragile. His critics — including Vander Plaats — argue that a congressman from northwest Iowa carrying the baggage of Washington won't hold up against Sand's "outsider vs. insider" general election framing.

Steen and Lahn are both making the electability argument from different angles. Steen says he's the conservative who can unite the base. Lahn says he's the outsider who can expand it. Feenstra says he's the one with the money and the infrastructure. All three could be right. Only one gets to test the theory.

Feenstra at 69% is the smart money. He has the cash, the establishment endorsements, and the frontrunner's advantages. But 69% is not 90%. The drift downward on the chart tells you the race is tightening. And the Steen/Lahn split at 16/16 means the anti-Feenstra vote hasn't consolidated yet. If one of them drops out and endorses the other before June 2, the math changes fast.

The wildcard: Trump hasn't endorsed anyone. Feenstra is asking for it. If Trump endorses Feenstra, this race is over. If he doesn't, or if he endorses someone else, Feenstra's 69% could drop to the 50s by primary day.

Watch the endorsement. Watch the debates (or lack thereof). And watch whether Steen or Lahn blinks first. In a three-way race, 69% is comfortable. In a two-way race, it's not.

Feenstra cash on hand: $4.3 million — more than every other Republican combined. (Iowa Capital Dispatch) Lahn self-funding: $2 million loan + $400K raised in a single month. (Iowa Capital Dispatch) Steen war chest: $336K, plus The Family Leader's organizing muscle. (Iowa Capital Dispatch) Cook Political Report moved the general election from "Leans Republican" to "Tossup" this week. Iowa hasn't elected a Democratic governor since 2006. Rob Sand is trying to end that streak. Debate attendance: Four of the five Republican candidates showed up to the Moms for Liberty event. Feenstra was the one who didn't. (Radio Iowa) Vander Plaats' warning: "Iowa history shows the state does not elect congressmen to be governor." He named three who tried and lost. Feenstra is trying to be the exception. (Iowa Public Radio) Primary date: June 2. General: November 3. Early voting starts in May.
