Pennsylvania Republicans won on lowering prices. Then came the Iran war.

Theory Briefing

• Republicans who flipped Pennsylvania seats in 2024 ran on cost-of-living relief, creating a concrete promise voters can measure them against.
• A looming Iran conflict introduces new economic pressures that could undercut the affordability message before midterms arrive.
• Seat-flipping members face the sharpest bind — their margins were thin and their voters' expectations specific.
• The 2026 midterms now hinge on whether foreign-policy events let these Republicans deliver on domestic economic pledges.
