Republican Rebellion Over Iran War Shows GOP Alarm Bells Ringing in Iowa

Several Republicans have ventured into opposition against the ongoing U.S. military campaign against Iran, reflecting possible alarm within the GOP as the midterms approach. On Tuesday, the House voted 220-204 to restrict U.S. military action against Iran, marking the third time the symbolic measure has been approved. Seven Republicans joined Democrats in the vote, including three who had previously supported the effort.

When asked for comment, a spokesperson for Thomas Massie highlighted the representative's long-standing opposition to military ventures in Iran without congressional approval, and the articles of impeachment filed against Secretary of Defense Pete Hegseth over alleged breaches of the War Powers Act. Iowa Representative Zach Nunn, who switched his stance on the resolution, stated that Congress "needs to have a stake in the game."

Mariannette Miller-Meeks of Iowa also voted for the resolution, arguing that the Iranian intervention was turning into "another forever war." The increased dissent among GOP members comes as concerns mount over the electoral implications of the Iran war, and as the Hawkeye State—won by Trump with a 13-point margin in 2024 and consistently Republican in recent years—becomes a key battleground in November.

Newsweek sought comment from the Republican lawmakers on Wednesday. The resolution, passed on Tuesday, calls for the removal of American troops from the region without congressional authorization—an effort aimed at pressuring the White House and Senate but without any immediate effect on the ongoing combat operations. The arguments put forth by the two Iowa lawmakers mirror broader concerns expressed by both parties as the Iran war, initially intended as a short operation, surpasses the six-month mark.

Nunn expressed his opposition on X, saying that he would not support another open-ended war, emphasizing the need to defend Americans, pressure Iran, and seek peace while ensuring Congress fulfills its constitutional duty. This marks a departure for Nunn, who last month campaigned alongside the Secretary of Defense. Hegseth asserted that the congressman was "willing to take the tough votes to do the right thing on behalf of our war fighters," according to a Des Moines Register report.

Miller-Meeks stated that she would not vote to "keep our soldiers in an open-ended war, with Iowans paying too much at the pump." She wrote on X that the Iranian regime and its nuclear ambitions had been "defanged." Both lawmakers' shifts align with their potential vulnerability in the upcoming elections. Analysis from the Cook Political Report indicates that both campaigns—Nunn's bid for Iowa's 3rd Congressional District and Miller-Meeks' for its 1st—are in "toss-up" territory.

With only three seats between Democrats and a majority in the House, these districts are among the party's top targets for potential flips that could secure control of Congress. In Iowa, Representative Ashley Hinson has launched an ad highlighting her pro-affordability policy priorities and her willingness to "reach across the aisle" and collaborate with Democrats on issues such as drug prices and health care for veterans.

Hinson is in a tight race to secure one of the state's Senate seats against state Representative Josh Turek, while several polls suggest Democrat Rob Sand holds a double-digit lead over Republican Zach Lahn in the gubernatorial race. Iowa has not elected a Democrat as governor since 2006, but former assistant attorney general Rob Sand appears to be gaining traction due to a campaign focused on government accountability, economic growth, and affordability.
