Iowa's 3rd Congressional District remains one of the state's more competitive House seats, with Republican incumbent Zach Nunn facing Democrat Sarah Trone Garriott in the November 2026 general election. Trone Garriott secured the Democratic nomination in the June 2 primary after consolidating party support following an earlier withdrawal and endorsement by state Rep. Jennifer Konfrst. The district carries a Cook Partisan Voting Index of R+2 and was won by Nunn by roughly four points in 2024. Race ratings from outlets such as Cook Political Report and Sabato's Crystal Ball classify it as a toss-up, while Inside Elections rates it Lean Republican. Trader consensus reflected in current pricing appears driven by the seat's marginal status during a midterm cycle and the Democratic nominee's rapid unification of her party's base.
