New Hampshire Republican John E. Sununu announced a campaign for US Senate on Wednesday, hoping to reclaim a seat he lost nearly two decades ago and boosting the GOP's chances of regaining a foothold in a region overwhelmingly represented by Democrats. Sununu, 61, is seeking the Republican nomination for the seat being vacated by US Sen. Jeanne Shaheen, a Democrat who ousted him in 2008. His decision sets up a Republican primary featuring two former senators: Scott Brown, who represented Massachusetts before moving to New Hampshire and losing to Shaheen in 2014, has been running since June, the AP reports.

"Maybe you're surprised to hear that I'm running for the Senate again. I'm a bit surprised myself," Sununu said in a video announcement. "Why would anyone subject themselves to everything going on there right now? Well, somebody has to step up and lower the temperature. Somebody has to get things done." National Republicans consider Sununu a strong candidate and one that allows them to go on the offensive as they look to hold their majority in the chamber next year.

  • Senate Republicans, who hold a 53-47 advantage, are defending seats in Ohio, Maine, and North Carolina against a slate of high-profile Democratic candidates. But Republicans are also on the offensive in places like Michigan, Georgia, and now, increasingly, New Hampshire—and if they flip one of those seats, it will likely put the chamber out of reach for Democrats until at least 2028.
  • Sununu must first win the primary though, and his past opposition to President Trump could be problematic. While Brown has aligned himself closely with Trump and served as his US ambassador to New Zealand, Sununu backed Nikki Haley in the 2024 Republican presidential primary, writing an op-ed titled "Donald Trump is a loser." "If he's our nominee, we're going to lose, and we're going to lose bad," he wrote.

  • Sununu served three terms in the US House before being elected to the Senate at age 38. He was the chamber's youngest member throughout his term, a fact he emphasized in a 2008 campaign ad that showed him sprinting up a steep mountain path. He's now the same age Shaheen was when she defeated him and is 16 years older than US Rep. Chris Pappas, the front-runner for the Democratic nomination.
  • Though Sununu has long been out of office, his name recognition remains high due to his family's political prominence. His father, John H. Sununu, is a former governor and former White House chief of staff. One of his brothers, Chris Sununu, served four terms as governor and flirted with a Senate campaign of his own in 2021. He also shot down a bid this cycle, saying he had spoken to the White House but opted against it.
  • Sununu has worked in the private sector since leaving Congress and New Hampshire Democrats have targeted his service on corporate boards, saying he "will work for corporations and special interests, not for Granite Staters," the Washington Post reports.
