The New Hampshire Senate race is shaping up as a closely watched contest in the 2026 election cycle, with implications for the balance of power in the U.S. Senate. The race features Democratic Representative Chris Pappas and former Senator John E. Sununu, both running campaigns marked by cautious messaging amid an electorate deeply influenced by attitudes toward former President Donald Trump.
Recent ratings from political analysts have shifted the race from “lean Democratic” to a “toss up,” reflecting growing uncertainty. Polls show the candidates in a competitive position, with Pappas holding modest leads of about 5 to 8 percentage points, though some surveys have shown them tied. Democrats are closely monitoring the contest because they face the challenge of flipping at least four Senate seats nationwide to regain control of the chamber, including two in states that President Trump won decisively in 2024. An upset in New Hampshire, a state that rejected Trump three times, could jeopardize those efforts.
Pappas, a four-term congressman, is conducting a subdued campaign that leans on voter dissatisfaction with Trump rather than advancing a detailed policy agenda. His priorities include measures such as banning stock trading for members of Congress, reducing the influence of dark money in politics, and supporting certain tax cuts and credits. However, he has steered clear of more contentious topics. For example, on immigration, he advocates for “comprehensive, common-sense reform” rather than more radical proposals, and while he has been a consistent supporter of Israel, he abstained from voting on an amendment to cut military aid to Israel during the recent conflict, drawing criticism from opponents. Pappas emphasizes standing up to Trump and his administration, portraying Sununu as a candidate aligned with the former president.
Sununu, by contrast, is seeking to balance appealing to Trump’s base with a more independent image. He highlights his past willingness to oppose the Republican leadership, citing his votes against parts of the Patriot Act. His campaign focuses on themes like congressional term limits and suspending lawmakers’ pay during government shutdowns, avoiding controversial issues and detailed policy proposals. Sununu downplays direct association with Trump while assuring voters he would represent New Hampshire’s interests independently. His well-known political family background and previous service in Congress give him strong name recognition.
Trump’s continued unpopularity in New Hampshire is a significant factor. A recent University of New Hampshire poll showed only 32 percent approval for Trump’s performance as president, with 67 percent disapproving. This widespread disapproval benefits Pappas, who centers his campaign on opposing Trump’s influence. Voters interviewed expressed strong negative views about Trump and concern over Sununu’s ties to the former president, although some indicated they remain open to supporting Sununu.
Despite the renewed competitiveness indicated by recent ratings and polling, some analysts and observers note similarities to the 2022 Senate race when incumbent Democrat Maggie Hassan was once considered vulnerable but ultimately won comfortably. While Sununu has narrowed the margin compared to past GOP challengers, the path to victory for Republicans remains challenging given the current political climate and Trump’s low approval in the state.
Overall, the New Hampshire Senate race reflects a contest influenced heavily by national political dynamics and voter attitudes toward Trump. Both candidates are running measured campaigns with limited ideological boldness, leaving the electorate to decide whether opposition to Trump or the appeal of a known Republican figure will prevail in the state’s closely watched contest.
