Senate
GOP leaders were unsuccessful with one Sununu, but they may get another.
While national Republicans failed to recruit former Gov. Chris Sununu into the open New Hampshire Senate race, ex-US Sen. John E. Sununu, brother of the four-term Granite State chief executive, has been traveling throughout New Hampshire and confirms that entering the race is under consideration.
Ex-Massachusetts Senator and 2014 New Hampshire Republican Senate nominee Scott Brown is an announced candidate, but he is trailing Rep. Chris Pappas (D-Manchester) in polling and currently would not make this open race a top-tier national campaign. A recent St. Anselm College poll (Aug. 26-27; 1,800 New Hampshire registered voters; online) found Rep. Pappas topping former Sen. Brown, 48-37 percent. Opposite state Sen. Dan Innis (R-Bradford), the Pappas lead expands to blow-out proportions, 48-30 percent.
Chris and John E. Sununu are the sons of former White House chief of staff in the George H.W. Bush Administration and ex-three term New Hampshire Gov. John Sununu. John E. Sununu served three terms in the US House, from 1997-2003, and was elected to the Senate, defeating then-Gov. Jeanne Shaheen (D), in 2002.
Six years later, Shaheen returned to unseat Sen. Sununu in the first Obama election and remains in office. Her announced retirement has placed the in-cycle New Hampshire seat into the open category.
New Hampshire is regarded as a swing state yet, except when facing the Sununu’s, Democrats typically win the competitive races. That paradigm changed, however, when former Sen. Kelly Ayotte (R), who was defeated for re-election in 2016, rebounded to win the Governor’s campaign last November. Because New Hampshire is one of two states that limit their Governors to two-year terms – Vermont is the other – Gov. Ayotte will again be on the ballot in 2026.
New Hampshire has not been overly friendly to President Trump, because he failed to carry the state in all three of his elections. The average Trump Granite State vote is 46.5 percent, and his closest finish, which occurred in 2016, saw him coming within three-tenths of a percentage point from overtaking Hillary Clinton. Despite running well nationally in 2024, the President still lost a 50.3 – 47.6 percent New Hampshire decision to Kamala Harris.
Prior to Gov. Sununu publicly declining to run for the Senate, he led Rep. Pappas in early polling. In late March, Quantas Insights, for example, found Gov. Sununu running ahead of Rep. Pappas by a substantial 53-44 percent margin. Whether John E. Sununu can bring the race back into contention remains to be seen, but it is likely he will poll much closer to Rep. Pappas than any other potential Republican candidate.
For his part, Pappas, who was elected to the House in 2018 from the state’s eastern 1st District, won before an electorate that had defeated more incumbents than any in the country during the period between 2004 and 2018. Rep. Pappas has been able to secure the district, however, averaging 53.2 percent of the vote in his four congressional elections.
Prior to his service in Congress, Pappas was an elected member of the state’s unique five-member Executive Council, which has veto powers over a Governor’s appointments along with other duties and responsibilities. He previously won election as the Hillsborough County Treasurer and to the NH House of Representatives.
Declaring for the Senate immediately after incumbent Shaheen announced her retirement, Rep. Pappas has maneuvered himself into position as the consensus Democratic candidate and will have little trouble in securing the party nomination in September of next year.
Should John E. Sununu decide to enter the Senate race, it will be interesting to see if Brown will step aside. Because the legislature did not act upon Gov. Ayotte’s proposal to move the state’s primary to an earlier month, the GOP nominee could be in a significant underdog position after a bruising primary since so little time remains between the Sept. 8, 2026, primary and the subsequent November general election.
A Pappas-Sununu race would likely become highly competitive, placing the seat in play for the GOP. Therefore, the John E. Sununu potential candidacy is a developing story worth attention.
