Iowa's 3rd congressional district, anchored in the Des Moines metro area, features Republican incumbent Zach Nunn facing Democratic state Senator Sarah Trone Garriott in the November 3, 2026 general election. Recent polling from late 2025 showed Trone Garriott ahead of Nunn by double digits in head-to-head matchups, reflecting the district's competitive suburban and urban voter base that delivered Nunn only a narrow 2024 victory. Both candidates advanced easily from their June 2 primaries, clearing the field with strong party support. Trader consensus on the Democratic edge aligns with these indicators and the seat's history of tight margins, though midterm turnout patterns and national conditions remain key variables that could shift the race.
