Political Positions
LiberalConservative
Economy & Taxes
Supports major tax cuts and a pro-growth tax code, including permanently extending the 2017/Trump tax cuts and protections for small-business deductions; champions a balanced budget amendment to restrict federal spending. Promotes tax credits and provisions framed as tax relief for families, farmers, and small businesses while advocating reduced federal spending and greater fiscal restraint.
Healthcare
Supports protecting and strengthening public programs like Medicaid and Medicare, expanding access to rural care and the healthcare workforce, and investing federal resources to lower costs and keep care local. Focuses on bipartisan, government-supported measures (rural health funding, workforce training, and resolutions to block cuts to Medicaid/SNAP) rather than proposals to privatize or repeal major programs.
Show moreShow less
Immigration & Border
Supports stronger border enforcement and expanded border security measures including more Border Patrol agents, detention capacity, and finishing the border wall; advocates removing dangerous illegal immigrants and extending Title 42 as tools to reduce illegal crossings and drug trafficking.
Abortion & Reproductive Rights
Opposes abortion and has supported state-level restrictions (including fetal heartbeat/6-week and other limits) while stating he supports some exceptions (for the health of the mother, and in some statements rape and incest). He has said he does not support a federal restoration of Roe and has described the issue as one for states, though he has faced criticism for on-camera remarks about a national ban.
Climate & Energy
Supports an all-of-the-above energy approach emphasizing American energy independence, expansion of domestic fossil fuel production and leasing, and strong support for biofuels (including year‑round E15 and biofuels incentives and infrastructure). Advocates market-driven energy development and regulatory changes to increase domestic production while backing tax incentives and R&D for low‑carbon biofuels.
Public Safety & Guns
Zach Nunn consistently supports strong Second Amendment protections, has sponsored legislation to block enforcement of federal gun regulations in Iowa, and has been endorsed/rated highly by pro-gun organizations. He has advocated for protecting gun rights in state and campaign statements and opposed local “gun-free zone” restrictions that limit carrying. His public record emphasizes defending gun ownership rights over enactment of new firearm regulations.

AINews Summary
Last updatedAug 7, 2026
Zach Nunn is in the news because his Iowa 3rd Congressional District race is being described as highly competitive and a major battleground in the 2026 midterms. Recent coverage says Democrat Sarah Trone Garriott has launched her first general election TV ad against him, while polling and race analysis still show the seat as a toss-up. The Libertarian candidate’s exit after a medical emergency may also reshape the contest, but Nunn remains the Republican incumbent on the ballot.
