(The Center Square) — Competitive races across Iowa are expected to determine partisan control of Congress in the 2026 midterm elections, where candidates are divided among affordability concerns, farming and tax policies.

Incumbent Rep. Zach Nunn, R-Iowa, is facing Democrat Sarah Trone Garriott in one of the tightest congressional elections in the country, according to most forecasters. The Cook Political Report ranks Iowa’s third congressional district as a “toss up,” which means either party has a good chance of winning.
