Iowa's 3rd Congressional District remains one of the most competitive 2026 House races, with Republican incumbent Zach Nunn facing Democratic state Sen. Sarah Trone Garriott after both secured their party nominations in the June 2 primaries. Nunn's 2024 reelection margin of roughly four points aligned closely with the district's partisan lean, prompting forecasters to rate the contest a toss-up or lean Republican. Recent surveys indicate Trone Garriott holding a lead in head-to-head matchups, contributing to trader consensus favoring a Democratic outcome. A Libertarian candidate's late entry adds minor vote-splitting uncertainty ahead of the November general election, though the race's path hinges primarily on turnout in the Des Moines metro area and broader midterm dynamics.
