Top 5 2026 New Hampshire House Races by Candidate Field Depth and FEC Filings

Public Records and Candidate Field Depth in New Hampshire's 2026 House Races

As of early 2025, the FEC has received filings from candidates in all five of New Hampshire's US House districts. The depth of each field varies considerably, from crowded primaries to presumed incumbents with minimal opposition. This piece ranks the five races by the number of declared candidates, party balance, and the likelihood of competitive general elections. Public records—including FEC Form 2 (Statement of Candidacy) and Form 1 (Statement of Organization)—form the basis of this analysis. Researchers and campaigns examining these races should verify filings directly via the FEC's electronic database or the New Hampshire Secretary of State's candidate listing.

1. NH-01: The Most Crowded Field

New Hampshire's 1st Congressional District, covering the eastern half of the state including Manchester, Rochester, and the Seacoast, boasts the deepest candidate pool. As of March 2025, at least five candidates have filed: two Republicans, two Democrats, and one Libertarian. Incumbent Republican Chris Pappas has not yet filed for reelection, but his campaign committee remains active. On the Democratic side, former Executive Councilor Andru Volinsky and state Senator Rebecca Perkins Kwoka have both filed. The GOP primary features former Trump administration official Matt Mowers and state Representative Joe Sweeney. The Libertarian candidate, Zachary Dumont, is a perennial candidate. This field depth suggests a highly competitive primary on both sides, followed by a general election that could see significant outside spending. Researchers would examine the candidates' previous vote shares, fundraising hauls, and any local endorsements from the Manchester Union Leader or the Seacoast media.

2. NH-02: A Competitive Open Seat?

The 2nd District, covering western and northern New Hampshire including Nashua, Concord, and the North Country, currently has four declared candidates: two Democrats and two Republicans. Incumbent Democrat Annie Kuster has not announced a retirement, but rumblings in Concord suggest she may step down. If she does, the open seat would attract additional entrants. The Democratic primary features state Representative Wendy Thomas and former state Senator Molly Kelly. The GOP field includes former state Representative George Lambert and businessman Jay Chadwick. The district leans Democratic but has a history of electing moderates. Researchers would focus on Kuster's decision timeline and the fundraising reports of the declared candidates. The North Country's independent voters could swing the general election.

3. NH-03: A Solid Democratic Hold with a Libertarian Wildcard

The 3rd District, a new seat created after the 2020 census, covers the southern tier from Salem to Keene. Incumbent Democrat Chris Pappas (who currently holds NH-01 but may switch districts) has not filed here. Instead, three Democrats and one Republican have filed. The Democratic primary includes state Senator Cindy Rosenwald, former state Representative Renny Cushing, and attorney Joe Foster. The lone Republican is former state Representative Steve Whalen. A Libertarian candidate, Darryl Perry, has also filed. The field depth is moderate, but the lack of a strong GOP challenger makes this race less competitive overall. Researchers would examine whether national Republicans recruit a stronger candidate before the filing deadline.

4. NH-04: Incumbent Advantage, But a Third-Party Presence

New Hampshire's 4th District, a rural and exurban seat in the western Lakes Region, is held by Republican incumbent Bob Giuda. He has filed for reelection. Two Democrats have filed: former state Senator Martha Fuller Clark and local activist Tom Watson. A Libertarian candidate, John Babiarz, rounds out the field. The field depth is moderate, but Giuda's incumbency and the district's GOP lean make the general election less competitive. Researchers would examine Giuda's committee assignments and any primary challengers that may emerge from the party's right flank.

5. NH-05: The Quietest Race So Far

The 5th District, covering the eastern Lakes Region and the White Mountains, is represented by Republican incumbent Eddie Edwards. He has filed for reelection. Only one Democrat, former state Representative and 2024 candidate Mindi Messmer, has filed. No third-party candidates have emerged. This is the shallowest field among the five races. The district is safely Republican, and Messmer's previous run ended in a 15-point loss. Researchers would monitor for additional Democratic entrants or a primary challenge to Edwards from the far right.

Comparative Analysis and Research Angles

When ranking these races by candidate field depth, NH-01 stands out for its sheer number of contestants and the potential for a competitive primary on both sides. NH-02 could vault to the top if Kuster retires. NH-03 and NH-04 have moderate depth but lack a strong general-election challenge. NH-05 is the least competitive by field depth, but incumbency dynamics could shift. Campaigns researching these races should examine each candidate's FEC filing history, previous campaign finance reports, and any public statements about their platform. Opposition researchers would look for past voting records, business ties, and social media footprints. The Libertarian candidates in NH-01, NH-03, and NH-04 could act as spoilers in tight races, a factor that has historically impacted New Hampshire elections.
