# New Hampshire U.S. Senate 2026
> [!success] Primary result — September 8, 2026
> **Chris Pappas (D) 65%** over Karishma Manzur. **John E. Sununu (R) 68.5%** over Scott Brown.
> November matchup for Jeanne Shaheen's open seat: **PAPPAS vs. SUNUNU**. Inside Elections moved the race from Tilt D to **Toss-Up** on September 3 after UNH showed Sununu 45-43.
## Snapshot
Open seat after Jeanne Shaheen's 2025 retirement announcement. The general election is a near-perfect tie: **Pappas 45, Sununu 44** (Emerson, March 2026). U.S. Rep. Chris Pappas (NH-01) is the clear Democratic frontrunner with $4.2M COH and has already reserved $9M in general-election TV from September 8. The Republican field is led by **[[John E. Sununu]]** — the former U.S. Senator (2003–2009), brother of former Gov. Chris Sununu — who led [[Scott Brown]] 48–19 in primary polling. Cook rates Lean D. This is the cycle's true battleground for the Democratic firewall.
> [!info] Status as of 2026-08-31 — written before the primary, kept as the record of what the field looked like going in
> **The ballots are set and nothing has changed the shape of the race.** The Sept 8 primary is the second-to-last of the entire cycle (only Delaware, Sept 15, comes after). Pappas faces only Karishma Manzur on the Democratic side; Sununu faces Brown on the Republican side. Note the September 8 date is doing double duty — it is also the last day Missouri courts can add questions to that state's November ballot, so expect the national political-news bandwidth that night to be split.
>
> Watch the Pappas TV reservation: **$9M booked to begin September 8**, i.e. the night of his own primary. That is a campaign treating the primary as a formality and buying the general early, which is a real signal about where the Democratic side thinks the risk is.
## Incumbent (retiring)
- **[[Jeanne Shaheen]]** (D) — senator since 2009. Former Governor of New Hampshire (1997–2003) — first woman elected governor of NH. Three Senate terms. Announced retirement 2025 (part of the Democratic retirement wave — Peters, Smith, Durbin, Shaheen, plus Lee/Booker holding).

🔴 **A four-sweep watch item closes here.** Since 2026-10-05 every Republican-side dollar recorded in this
race had been an attack on [[Chris Pappas]], and the standing trigger was *whether anyone buys a positive
dollar for [[John E. Sununu]]*. **[[America PAC]] did, on file 2019090: $6,622.01 through IMGE LLC** —
paired to the cent against $6,622.00 opposing [[Chris Pappas]], which is the split-to-the-cent invoice
pattern rather than a strategy change. **The trigger has fired, and the amount is 0.35% of the day's
money in this race.**

## Intel notes
- **The Emerson tie (Pappas 45, Sununu 44)**: this is the cleanest Senate battleground of the cycle. The race will determine whether Democrats hold the Northeast firewall or break open the competitive map.
- **John E. Sununu's return**: the former senator lost to Shaheen in 2008 by 7 points. His return 18 years later creates an unusual "rematch by proxy" — Sununu vs. a Democratic seatholder originally elevated by defeating *him*. Narrative hook.
- **Chris Sununu's non-candidacy**: the former Governor was the highest-profile prospective candidate. His decision not to run (preferring to stay out of Washington) creates the opening for his brother John. Worth tracking if Chris endorses.
- **Scott Brown structural weakness**: Brown has now lost Senate races in two states (MA 2012, NH 2014). A third Senate bid at 19% in primary polling is essentially a vanity run.
- **Pappas's $9M TV pre-reservation**: extraordinary general-election commitment nine months before the election. Signals Democratic confidence and locks in lower ad rates before demand surge.
