More Republicans are turning on Iran war as midterms come into view

What Happened

The US House of Representatives considered its sixth war powers resolution intended to force Donald Trump to withdraw troops from the conflict with Iran. Three Republicans who had not supported previous efforts voted for passage: Mariannette Miller-Meeks and Zach Nunn of Iowa, and Nancy Mace of South Carolina. They joined four Republicans who had already backed earlier resolutions — Thomas Massie of Kentucky, Warren Davidson of Ohio, Tom Barrett of Michigan and Brian Fitzpatrick of Pennsylvania — bringing total Republican defectors to seven. Earlier that day, Thomas Massie proposed a resolution to impeach Defense Secretary Pete Hegseth, alleging constitutional transgressions including prosecuting the war against Iran without congressional authorization. The article reports Trump has ignored the sole war powers resolution to pass both the House and Senate. The stated reasons from Miller-Meeks and Nunn include opposition to an open-ended war and concerns about costs to Iowans.

Why It Matters

The growing Republican defections on war powers resolutions underscore election-year pressure over an unpopular conflict with Iran. Democrats are using these votes to force Republicans on the record, and vulnerable Republicans from battleground districts such as Miller-Meeks and Nunn are signaling distance from Trump's Iran policy ahead of the 3 November midterms. The internal GOP split also threatens Trump's ability to sustain the conflict without congressional authorization and gives dissident Republicans leverage to challenge his allies, including Defense Secretary Hegseth.

Watch For

The House was scheduled to meet Thursday for the last session before the 3 November midterm elections, but Republican leaders canceled Thursday's votes and sent lawmakers home early. This may delay any vote on Massie's impeachment resolution. Monitor whether the House reconvenes before the midterms, whether the impeachment resolution advances, whether additional Republicans defect on future war powers resolutions, and the 3 November midterm results.
