Democrats win three Iowa U.S. House seats to shift delegation

Iowa’s Congressional Shift

Iowa’s politics changed significantly as voters flipped three of the state’s four U.S. House seats from Republican to Democratic control. According to reports from Radio Iowa, the results leave the state’s delegation with three Democrats and one Republican in Washington, D.C. for the upcoming term.

Democrat Christina Bohannan defeated incumbent Republican Congresswoman Mariannette Miller-Meeks in the first congressional district. This was Bohannan’s third race against Miller-Meeks; she previously trailed Miller-Meeks by just 799 votes in 2024. This year, the margin shifted dramatically, with unofficial results showing Bohannan winning by more than 30,000 votes.

“Iowans have sent a message,” Bohannan told supporters in Iowa City. “They have reminded us that in America democracy is alive, that our votes really do make a difference.”

The Changing Delegation

In the second congressional district, Democrat Lindsay James secured a win over Republican Joe Mitchell. This seat was vacated by Republican Ashley Hinson, who opted to run for the U.S. Senate. James said a lot of people told her when she launched her campaign that they didn’t think a Democrat could win the seat. “When I talked to people about the importance of this moment, not only for Iowa’s second congressional district, but for the life of our country, I often was met with, ‘Well, Iowa’s broken too many hearts over the years,’” James told Radio Iowa. “And my response was always, ‘Well, we’re here to repair that.’”

The third congressional district also saw a change in leadership. Democrat Sarah Trone Garriott unseated Republican Congressman Zach Nunn, winning by a 9% margin according to unofficial results. The seat has flipped three times since 2016. Trone Garriott framed her campaign around the necessity of restoring healthcare and addressing economic concerns, specifically mentioning the impact of tariffs.

The Republican Perspective

While the state’s map shifted, Republican Chris McGowan won the fourth congressional district, defeating Democrat Dave Dawson by approximately 50,000 votes. The seat was open following the decision of U.S. Representative Randy Feenstra to run for Governor of Iowa. McGowan, set to be the lone Republican in the state’s House delegation, acknowledged the reality of his position in the minority party.

“There is no one lower on the totem pole than a freshman member of congress in the House in Washington, D.C.,” McGowan said during his victory speech in Sioux City. He identified his primary legislative focus as addressing the national debt, which has reached $40 trillion.

The Republican incumbents who lost their seats expressed a mix of disappointment and resolve. In a written statement, Mariannette Miller-Meeks noted that the country remains at a crossroads. Similarly, Zach Nunn addressed supporters at the Iowa GOP’s election night gathering, emphasizing that the loss would not end his engagement in public service. “Not only do we rebuild, we fight forward because giving up on Iowans is never in the cards,” Nunn said.

For voters, the stakes remain tied to the immediate economic pressures of healthcare costs and trade policy.
