## Seven Republicans break with Trump on Iran
The House voted 220-204 on Tuesday to limit U.S. military action against Iran. Seven Republicans joined Democrats, including three voting this way for the first time.
## Iowa lawmakers cite forever war concerns
Representatives Zach Nunn and Mariannette Miller-Meeks both voted for the resolution, warning the operation risks becoming another endless conflict without congressional oversight.

> I will not support another open-ended war.
## Nunn shifts stance on war powers
Nunn, a military veteran with over 700 combat hours, said Congress needs to fulfill its constitutional responsibility. He campaigned with Defense Secretary Hegseth just last month.

> Congress needs to have a stake in the game.
## Miller-Meeks warns of economic pain
Miller-Meeks argued the war drains resources while Iowans struggle with high gas prices. She called on the president to present an exit plan to Congress.

> The President needs to present a plan to Congress and the American people for how this ends.
## Iowa races now toss-ups for GOP
Cook Political Report rates both Nunn's and Miller-Meeks' races as toss-ups. Democrats target their districts as top flip opportunities with only three seats needed for House control.
## Broader Iowa Democratic momentum
Democrat Rob Sand leads in gubernatorial polls by double digits, and Ashley Hinson faces a competitive Senate race. Iowa hasn't elected a Democratic governor since 2006.
## War extends past six-month mark
Originally planned as a brief operation, the Iran conflict now stretches beyond six months with no clear end date, fueling bipartisan concerns about mission creep.
## Key takeaway

Republican defections on Iran war votes reveal internal party divisions driven by electoral vulnerability in key swing districts.
