Representative Zachary Nunn, Republican from Iowa

Zachary Nunn

Iowa's 3rd congressional district

IA-3 Midterms Intelligence

Nunn sits in one of the House’s truest swing seats: an R+4 Des Moines-centered district where Democrats still pull 48.1% and competitiveness clocks in at 96%. A first-term incumbent no longer, he survives by fusing suburban pragmatism with Iowa conservatism—strong on agriculture, finance, and China competition, while keeping a moderate enough profile for college-educated homeowners. IA-03 is more affluent and younger than the Iowa stereotype, with median income at $80,844, but it remains culturally center-right and has trended modestly Republican.

For advocates, this is a persuasion district, not a base-mobilization one. The winning frame is economic security: cost of living, farm resilience, small-business certainty, and protecting local institutions from global shocks. Healthcare is a live undercurrent—despite low uninsured rates, obesity is 37.2%—but messages work best when tied to workforce productivity and family stability, not ideology. Nunn will be highly sensitive to anything that reads as anti-ag, anti-suburban, or too partisan; campaigns that pair business credibility with local impact can move him or box him in.

Representative Zachary Nunn represents Iowa's 3rd congressional district, serving 816,359 constituents. The district has an estimated median household income of $80,844 and an unemployment rate of 3.9%.
