Sununu, Pappas face off for New Hampshire's open Senate seat

Ayotte faces Warmington in governor’s race; two House seats on ballot

New Hampshire voters head to the polls in a midterm election that will decide an open U.S. Senate seat, two House districts, the governorship, and a statewide ballot measure. The state is one of several that could determine whether Democrats wrest control of the U.S. Senate from Republicans, and the governor’s race will help determine whether Republicans maintain their “trifecta” hold on the governorship and both chambers of the Legislature, according to the Associated Press.

The Senate seat, held by a Democrat for a decade and a half, is open after Democratic Sen. Jeanne Shaheen — first elected to the Senate in 2008 and a former governor — announced in 2025 that she would not seek a fourth term.

Democrat Chris Pappas, who has represented New Hampshire in the U.S. House since 2019, would be the first openly gay U.S. senator if elected. He faces Republican John E. Sununu, who has served in both chambers of Congress and was ousted from the Senate by Shaheen in the 2008 election. Sununu comes from a storied political family; his father and brother were governors of the state.

Pappas has far outraised Sununu, amassing a war chest of more than $23.7 million compared with the Republican’s $5.7 million as of mid-October. Tens of millions more in outside spending have poured into the race, with outside groups spending more to oppose Pappas than Sununu.

Housing costs have risen rapidly in the state in recent years, and both candidates have made affordability a central issue of their campaigns.

Both candidates have also distanced themselves from their own political parties. President Donald Trump endorsed Sununu in February, but the Republican has sought to distance himself in recent weeks from the president, whose plunging approval rating could represent a liability in a race that increasingly appears to be a referendum on the presidency. Pappas, a moderate Democrat who defeated a progressive challenger in the primary, has similarly tried to emphasize his independence from some of the party’s establishment figures, highlighting instead his appeal to independent voters.

In the 1st Congressional District, Stefany Shaheen, a Democrat and the outgoing senator’s daughter, is facing Republican Anthony DiLorenzo to occupy Pappas’ seat. In the 2nd District, incumbent Democratic Rep. Maggie Goodlander is in a rematch against Republican Lily Tang Williams, who was Goodlander’s GOP opponent in 2024.

All of New Hampshire’s seats in Congress have been occupied by Democrats since 2017, and the state has voted for a Democrat in every presidential race since 2004. New Hampshire’s voters have nonetheless shown a willingness to split their votes between parties: the state has had a Republican governor since 2017.

New Hampshire is one of only two states whose governors serve two-year terms. Incumbent Gov. Kelly Ayotte, a Republican who was first elected in 2024, is defending her seat against Democrat Cinde Warmington, a former member of the state’s Executive Council.

Polls close at different times in different parts of the state — at 7 p.m., 7:30 p.m. and 8 p.m. In some towns with only a handful of residents, polls open at midnight on Election Day and close a few minutes later once all voters have cast a ballot.

The Associated Press will provide vote results and declare winners in races for U.S. Senate, governor, U.S. House, a statewide ballot measure, state Senate, state House and Executive Council. New Hampshire runs elections at the town and city level, with 238 separate jurisdictions administering local elections; the jurisdictions vary in how and when they release results. Most of the larger jurisdictions release all or nearly all of their results from both absentee and in-person Election Day voting in their first vote updates of the night, while other large jurisdictions release a mix of results throughout the night.

More than 620,000 votes were cast in the 2022 race for the U.S. Senate, and about 10% of all ballots cast in New Hampshire’s 2022 election were cast early or by absentee ballot. In the 2024 presidential election, the state reached 50% of votes reporting at 10:12 p.m. on Election Day and 90% of votes reporting at 1:42 a.m.

The AP does not make projections and will declare a winner only when it is determined there is no scenario that would allow a trailing candidate to close the gap. If a race has not been called, the AP will continue to cover any newsworthy developments, such as candidate concessions or declarations of victory, and will make clear that it has not yet declared a winner. There are no automatic recounts in New Hampshire, but a candidate may request and pay for a recount if the margin is 20% or less; the AP may declare a winner in a race subject to a recount if it can determine the lead is too large for a recount or legal challenge to change the outcome.
