Incumbent Republican Zach Nunn faces Democratic state Sen. Sarah Trone Garriott in Iowa’s 3rd congressional district on November 3, 2026. The seat ranks among the most competitive House races, with Nunn holding a narrow 2024 victory margin in a district that leans only slightly Republican by partisan voting index. Traders appear to weigh national midterm dynamics, where the opposition party often gains ground, alongside Garriott’s established record in red-leaning areas and early general-election advertising launched by Democrats in early August. Limited recent polling shows a close contest, yet prediction-market pricing reflects sustained support for the Democratic nominee amid broader expectations of House turnover. Both candidates advanced unopposed in June primaries.
