New Hampshire voters set to formalize Ayotte-Warmington rematch as primary season closes

New Hampshire voters go to the polls Tuesday to close out one of the country's last September state primaries, and at the top of the ballot the outcome is barely in doubt. Republican Gov. Kelly Ayotte faces two little-known intraparty challengers as she seeks a second two-year term, while Democrat Cinde Warmington is running unopposed for her party's nomination. Barring a stunning upset, both will emerge Tuesday night as their parties' nominees for a general election that is already eight months in the making.

What the primary lacks in suspense at the gubernatorial level, it makes up for in stakes. New Hampshire is one of only two states that elects a governor every two years rather than four, meaning the race is a permanent fixture of the state's political calendar. It also arrives as Republicans and Democrats nationally are testing dueling messages — economic populism versus incumbent stability — heading into the November midterms, with President Trump's Labor Day proclamation predicting a "bold new era" for American workers even as Democratic candidates across the map, including Warmington, have built campaigns around the cost of housing, groceries and electricity.

The numbers

Ayotte enters the fall with a significant financial and polling advantage. A University of New Hampshire Survey Center poll released Aug. 27 found Ayotte leading Warmington 49 percent to 39 percent in a hypothetical general-election matchup, with 9 percent undecided — a lead that had grown five points since June. The same survey, of roughly 1,900 likely voters conducted Aug. 20-24 with a margin of error of 2.1 percentage points, put Ayotte's job approval at 49 percent approve, 42 percent disapprove, a net rating of positive 7 that had risen from even in July. Housing remained the issue New Hampshire residents most often named as the state's top problem, the survey found, while the share citing taxes was at its highest point in more than two decades.

Money tells a similarly lopsided story. According to campaign finance filings reported in June, Ayotte had raised roughly $3.7 million since launching her reelection bid, including $1.6 million so far in 2026, and was sitting on about $2 million in cash on hand. Warmington had raised about $635,000, nearly all of it collected since she entered the race in February — a pace her own campaign has acknowledged trails what New Hampshire's last two Democratic gubernatorial nominees had banked by the same point in their campaigns. Ayotte has already put more than $1 million behind television and streaming ads; Warmington's paid media spending was reported at roughly $9,000.

Tuesday's ballot extends well beyond the corner office. New Hampshire is also nominating candidates for an open U.S. Senate seat, where Republicans John Sununu and Scott Brown and Democrats Chris Pappas and Karishma Manzur are competing, and for both of the state's U.S. House seats. Down-ballot, all 400 seats in the New Hampshire House of Representatives, all 24 state Senate seats and all five seats on the Executive Council are on the primary ballot as well, making it — turnout aside — one of the largest single-day candidate-selection events in the country this cycle.

How the matchup came together

Ayotte, a former U.S. senator and state attorney general, won the governorship in 2024 after Republican Chris Sununu declined to seek a fifth term, and her first term has been shaped by her willingness to break with parts of her own party, including vetoes of several bills favored by legislative Republicans. Her campaign has emphasized education funding, public safety and housing initiatives from her first two years in office. No prominent Republican chose to challenge her from within the party; her only primary opposition comes from Shaun Fife and Robert Wayne McClory, neither of whom has mounted a visible statewide campaign.

Warmington, a health care attorney who spent four years on the state's Executive Council, is making her second run at the governorship after losing the 2024 Democratic primary to Joyce Craig, who went on to lose the general election to Ayotte. Warmington entered this year's race in February framing her candidacy around affordability, and no other Democrat filed to oppose her, clearing her path to the nomination without a contest. Her candidacy has also drawn scrutiny over her prior work as a lobbyist for Purdue Pharma during the opioid crisis, an issue her rivals raised repeatedly during her first bid and that she addressed again this year in a campaign video distancing herself from her former client's conduct.

The race is also notable for what it is not: New Hampshire's last late-season state primary. Ayotte signed House Bill 481 into law in May, moving future state primaries — for governor, the Executive Council, the state Senate and the state House — from September to June starting in 2028, in the hope of giving non-incumbent candidates more time to campaign before a general election. The presidential primary, which cements New Hampshire's first-in-the-nation status, is unaffected.

"The prices of groceries, housing, electricity and property taxes are crushing working families," Warmington said in a statement announcing her campaign in February. "Kelly Ayotte is making life in New Hampshire even more expensive."

Who is watching, and what analysts are saying

New Hampshire's governorship has been held by Republicans since 2017, and Democrats view it, along with the open Senate seat, as central to their hopes of demonstrating momentum in a swing state ahead of November. But strategists and academics tracking the race describe the top-of-ticket primary itself as largely an afterthought compared with the contested Senate and House primaries occurring the same day. John Lappie, a political science professor at Plymouth State University, said Ayotte's political positioning — governing, as he put it, in a manner reminiscent of her popular predecessor — has left Democratic challengers with less room to maneuver than they might otherwise have. "She certainly doesn't have the advantages that former Gov. Chris Sununu had," Lappie said of Ayotte's political inheritance, while noting she has nonetheless sustained comparable approval numbers.

Warmington's advocates argue the fundraising and polling gap understates her competitiveness, pointing to her campaign's contention that nearly all of her financial support has come from inside New Hampshire and that most of her individual donors are giving less than $100 — a contrast, they argue, with Ayotte's fundraising, which state filings show draws roughly half its total from businesses and organizations rather than individual donors. Whether that argument resonates with voters will not be tested until the general election; Tuesday's vote functions mainly to formalize a matchup that has effectively been set since Warmington's February launch and Ayotte's filing for reelection in June.

What happens next

Polls close across New Hampshire's roughly 300 towns and cities at hours set by local election officials, with most closing between 7 and 8 p.m. Eastern. Assuming Ayotte and Warmington win their primaries as expected, the general election campaign will run through Nov. 3, giving both candidates nearly two months to make their case in a state that has increasingly split its ticket between a Republican governor and Democratic federal representation. The results will also settle nominees in the state's competitive Senate primary and in the 2nd Congressional District, where freshman Democratic Rep. Maggie Goodlander is expected to advance to a rematch against Republican Lily Tang Williams, who lost to Goodlander two years ago.

For national party strategists, New Hampshire's gubernatorial race is likely to be watched less for its primary-night drama than for what the fall campaign reveals about whether an affordability message can overcome an incumbent with positive approval ratings in a state Democrats need to hold competitive ahead of 2028. The Aug. 27 UNH survey suggested that test is currently favoring Ayotte, but campaign officials in both parties have said they expect the race to tighten as spending increases through the fall.
