Iowa Senate election results: Republicans maintain 29 seats, six uncalled

“If there is any kind of, call it whatever you want, a blue wave, a historical trend that manifested itself, it will come crashing against the Iowa Legislature, and there it will end in public,” Democrat Rob Sand said, according to the Des Moines Register. Iowa Public Radio reported that as of 1:20 a.m. Wednesday, Republicans held 29 Iowa Senate seats to Democrats’ 15, with six races left to call — enough for the GOP to keep control of the chamber.

The Senate contest is only half of Iowa’s 50-seat upper chamber this cycle. In 2026, 25 seats were on the ballot: the odd-numbered districts, while even-numbered districts were not. Before results came in, Republicans already knew 21 members of the next Senate and Democrats knew 10, Iowa Public Radio reported. The chamber’s supermajority threshold is 34 seats; Republicans entered election night with 32 elected members, 17 for Democrats and one Republican-held vacancy.

The math that keeps Republicans in charge

The early returns make the majority safe, even if the supermajority is not. With 29 Republican seats called and six still undecided, the GOP is already above the 26-seat majority line; only a clean sweep of all six remaining races would put Republicans at 35 and back above 34, according to the arithmetic in Iowa Public Radio’s results.

Six candidates ran unopposed, Iowa Public Radio reported: Republicans Kevon Alons in District 7, Annette Sweeney in District 27; Democrats Tony Bisignano in District 15, Timi Brown Powers in District 31, Meghann Foster in District 43 and Janice Weiner in District 45. The remaining called seats span both parties across the state, from Jeff Taylor in District 2 to Jeff Reichman in District 50.

Divided government, different readings

The Des Moines Register framed the night as a “blue wave” that reached Iowa even as Republicans kept the Legislature. Democrats flipped key federal and statewide races, the Register reported: Josh Turek defeated Ashley Hinson for the U.S. Senate seat, Rob Sand defeated Zach Lahn for governor, and Democrats won congressional races in the 1st, 2nd and 3rd districts. Nate Willems also narrowly led incumbent Brenna Bird in the attorney general race, while several contests remained unsettled.

“When I grew up here, and all the time I was in office, too, Iowa was sort of in balance: Sometimes Democrats would win more, sometimes Republicans, but there was always a good mix,” former U.S. Sen. Tom Harkin, a Democrat, told the Des Moines Register. “It was only lately that Iowa went all for a supermajority of one party, and I think Iowans have recognized that’s not helpful, not good for the state.”

Republican Party of Iowa Chair Jeff Kaufmann offered a starker assessment to the Register.

Republican Party of Iowa Chair Jeff Kaufmann said he was not going to sugarcoat it. It was a disappointing evening, he said, and there was no doubt about it.

Even so, Kaufmann conceded the practical effect of the Senate result when Sand claimed the governor’s office: the “red wall” is the Iowa Legislature. AP News carried the official 2026 Iowa election results and race calls through its election results project, but the early Senate picture remained the same: Republicans 29, Democrats 15, six uncalled.

What the six uncalled races still decide

What is not yet known is whether Republicans reach the 34-seat supermajority or Democrats claw closer to parity. Iowa Public Radio’s list of known next-Senate members already includes Democrats such as Sarah Trone Garriott in District 14, Janet Petersen in District 18 and Art Staed in District 40, alongside Republicans from Tim Kraayenbrink in District 4 to Mark S. Lofgren in District 48. The six remaining calls will determine whether the next Senate is a comfortable Republican majority or a near-supermajority — and whether the divided government Sand described has a narrower or wider gap to bridge.

For now, the balance Harkin described is the one voters produced at the top of the ticket, while the chamber that will write the budget and vote on the governor’s appointments stays in Republican hands.
