# IA-03 (2026) — Zach Nunn vs. Sarah Trone Garriott
> [!success] Primary result — June 2, 2026
> **Neither primary was contested.** [[Zach Nunn]] (R) and [[Sarah Trone Garriott]] (D) were both unopposed.
> November: **Nunn vs. Trone Garriott**. Cook: **Toss Up**. The field-clearing this page anticipated in early 2026 held all the way to the ballot on both sides — unusual in a Toss Up seat, and a sign both parties settled on their candidate early rather than spending the spring on a primary.
## Snapshot
Iowa's 3rd Congressional District — Des Moines metro plus southwest Iowa. Republican [[Zach Nunn]], a combat-aviator sophomore incumbent, is running for a third term with Trump's "Complete and Total Endorsement" after briefly flirting with a 2025 gubernatorial bid. His Democratic opponent — State Senator **[[Sarah Trone Garriott]]** — was the consensus nominee after the D field cleared around her in early 2026, and went through the June 2 primary unopposed. Trone Garriott **outraised Nunn** in Q1 2026 ($1.69M to $1.26M) — a historic pattern break in R+2 Iowa. **Cook: Toss Up. Polymarket: 71% D.**
## Incumbent — Zach Nunn (R)
Combat aviator, [[Air Force]] Reserve officer, sophomore Republican (2nd term). Defeated Lanon Baccam (D) 51.9%–48.1% in 2024 — a **3.8-point margin**, running roughly even with Trump's district-level performance. Briefly considered running for governor in mid-2025 but announced 2025-07-14 — "after a discussion Friday with President Donald Trump" — that he would stay in IA-03. Trump issued a "Complete and Total Endorsement" in early 2026. **Unopposed in the June 2 GOP primary.**
## Democratic primary — June 2, 2026
Presumptive nominee: **State Sen. Sarah Trone Garriott** (D-West Des Moines).
- Lutheran pastor (M.Div.); Swarthmore undergraduate
- Flipped a Republican-held Iowa Senate seat in 2020
- In 2022 she defeated then-Senate President Jake Chapman (R) by 3 points while [[Kim Reynolds]] carried the same seat by 7 — **10-point crossover performance**, the strongest Iowa Democrats have seen in recent cycles
- Change Research poll showed Trone Garriott leading Nunn 53%–40% — the strongest D performance tested against him
**Field consolidation:**
- Iowa House Democratic Leader **Jennifer Konfrst** suspended her IA-03 campaign 2026-01-26 and endorsed Trone Garriott
- **Xavier Carrigan** disqualified from the June ballot via March 28, 2026 state panel decision; now plans to run as independent in November general
- Two nominal candidates remain on primary ballot (Tracy Limon, Easton Wolfe) but primary is effectively uncontested
Cook's March 2026 move to Toss Up **explicitly cited Trone Garriott as frontrunner** — a rare instance of a rating shift tied directly to challenger quality.
## Republican primary
Nunn unopposed.
## Ratings
- **Cook Political Report**: Toss Up (shifted to Toss Up March 2026, citing Trone Garriott's primary frontrunner status)
- **Cook PVI 2025**: R+2
- **Polymarket**: Democrats 71% (late April 2026) — notably bullish vs. Cook's 50-50 framing
- **Sabato's Crystal Ball**: TBD
- **Inside Elections**: TBD
## Key dates
- **2026-06-02** — Iowa primary (Trone Garriott effectively coronated D-side; Nunn unopposed R-side)
- **2026-11-03** — General election
## Money (Q1 2026)
| Candidate | Q1 Raised | Q1 Cash on Hand |
|---|---|---|
| Nunn (R) | $1.26M (incl. JFC $350K, [[Leadership PAC]] $20K) | **$3.04M** |
| Trone Garriott (D) | **$1.69M** | $2.19M |
- Trone Garriott outraised Nunn by $430K in Q1 (35% advantage)
- Nunn retains **$850K cash-on-hand lead** despite being outraised
- Trone Garriott's 2025 full-year raise: ~$1.4M; $845K COH at year-end — "the most for a challenger in the history of IA-03 heading into the election year"
## Intel notes
- **Historic pattern break**: Republican incumbents almost never get outraised in +2 R Iowa districts in Q1 of an election year. Trone Garriott's $1.69M haul is a leading indicator of grassroots energy (Q1 fundraising correlates with November turnout in recent cycles).
- **Crossover quality challenger**: Trone Garriott's proven +10-point crossover in a Reynolds-carried district is the single most important fact of this race. She is effectively the only Iowa Democrat who has shown she can pull a Reynolds voter in a competitive district.
- **Trump's dual move**: Trump talked Nunn out of the governor race in July 2025, then endorsed him for reelection — a classic Trump signal that he sees the House seat as defensible.
- **Republican primary vacuum**: No MAGA challenger to Nunn despite his narrow 2024 margin. Signals GOP establishment consolidation.
- **Polymarket vs. Cook divergence**: 71% D on Polymarket vs. Cook's Toss Up (50-50) framing — markets pricing in Trone Garriott quality + Q1 money + Konfrst consolidation; Cook ratings move more slowly.
- **Carrigan independent wildcard**: The disqualified-then-independent Xavier Carrigan could siphon D-leaning votes in November. Low probability but real.
- **Nunn at MAGA Nation** (2026-04-14): Spoke at MAGA Nation event on Iran and immigration — doubling down on the Trump alliance rather than distancing.
