Iowa's 3rd Congressional District remains one of the most competitive 2026 House races due to its R+2 partisan voter index and narrow 2024 margin for incumbent Republican Zach Nunn. Both parties have consolidated behind unopposed nominees ahead of the June 2 primaries, with Democrat Sarah Trone Garriott drawing national Democratic Congressional Campaign Committee support and early polling that shows her competitive or ahead. Trader consensus on the Democratic nominee at 56.5 percent reflects midterm dynamics in suburban swing districts, while the Republican share near 49 percent accounts for Nunn's incumbency and fundraising edge. Forecasters rate the seat a toss-up or lean Republican, highlighting how national trends, turnout in the Des Moines area, and fall campaigning could shift the outcome before the November general election.
