- He is an active-duty Air Force Reserve officer and former NSC staffer under the Obama and Trump administrations — a bipartisan national security background unusual for a freshman Republican.

Political Profile
Zach Nunn's 2022 win over Cindy Axne in Iowa's 3rd District was part of a broader Republican breakthrough in suburban Iowa — a pattern that has made the Des Moines suburbs significantly more competitive for Republicans than they were in the Obama era. His Air Force background and national security focus give him credibility on defense issues that help him in a district with significant federal employment and defense contractor presence. His state Senate experience before Congress gives him the legislative background that many freshman members lack.
Iowa's 3rd District is unusual in the 2020s Midwest: the Des Moines metro has some of the characteristics of growing Sun Belt suburbs (young professionals, college-educated, growing diversity) while the surrounding rural communities are among the most Republican in the state. Nunn's ability to thread this needle — maintaining conservative credentials for primary voters while pursuing bipartisan infrastructure and agricultural investments for general election credibility — will determine whether he can build the kind of long-term incumbent advantage that makes competitive seats safer over time.
Career Timeline
Policy Positions
Air Force Intel Officer in Congress
Zach Nunn grew up in Iowa and built a career in Air Force intelligence, including work with the CIA on national security matters. He served in the Iowa State Senate before winning his congressional seat in 2022 by defeating Democratic incumbent Cindy Axne. His military and intelligence background differentiates him from typical suburban Republican politicians and gives him credibility on national security issues that can be valuable in a swing states.
Suburban Des Moines — Swing Territory
IA-3 covers the Des Moines suburbs including Ankeny, West Des Moines, and Urbandale, plus agricultural counties in southwestern Iowa. The district has a mix of college-educated suburban voters, insurance and financial services workers (Des Moines is a major insurance hub), and rural communities. Suburban voters have trended Democratic in presidential years but the Trump realignment has moved IA-3 rightward overall, creating an R+2 lean.
Prime Democratic Target in Midterm
IA-3 is consistently on the DCCC's target list and in a favorable environment for Democrats — a midterm with a Republican president — it could flip. Nunn's slim 2022 margin and the suburban nature of the district make it competitive. Watch the generic ballot tracker (Democrats +6 as of May 2026) for the national tailwind. Democrats need strong candidate recruitment focused on economic concerns, healthcare, and tariff impacts on Iowa agriculture. See the full House 2026 competitive seats tracker.
