A former Republican Senator has upended the election landscape in New Hampshire’s U.S. Senate race, launching a re-election bid that has immediately positioned him as a frontrunner for the Republican nomination. John E. Sununu, who last held office over 16 years ago, announced his candidacy for the seat formerly held by retiring Democratic Senator Jeanne Shaheen, sparking immediate speculation about his potential to flip the Senate seat to the GOP.

Sununu’s entry into the race has drawn attention due to his family’s political legacy and the reported involvement of President Trump, though no formal endorsement has been announced. White House meetings involving Sununu and Trump have fueled rumors about the president’s influence, despite their historically strained relationship. Sununu’s campaign video, released online, frames his return as a bid to “lower the temperature” in Washington and restore fiscal responsibility.

The Republican primary faces significant challenges, with Sununu competing against former Senator Scott Brown, who narrowly lost to Shaheen in 2014. Recent polling suggests Sununu holds a substantial lead over Brown among likely GOP voters, with a 50% favorable rating compared to Brown’s 30%. Analysts note that Sununu’s family name and political experience could give him an edge, though his success hinges on securing broader party support.

While Trump’s endorsement remains unconfirmed, other figures have endorsed Sununu, including South Carolina Senator Tim Scott and New Hampshire State Representative Michael Granger. Granger highlighted Sununu’s voting record, particularly his opposition to the PATRIOT Act, as a key factor in his decision. Meanwhile, Brown has criticized Sununu’s candidacy but acknowledges the need for a strong GOP contender to challenge Democratic incumbent Chris Pappas.

The race underscores shifting dynamics within the Republican Party, with electability increasingly prioritized over loyalty. As Sununu seeks to reclaim his Senate seat, the outcome will depend on whether Trump and other key allies fully back his campaign.
