CONCORD, N.H. — New Hampshire Republican John E. Sununu announced his campaign for the U.S. Senate on Wednesday, aiming to regain a seat he lost nearly 16 years ago and to strengthen the GOP's standing in a predominantly Democratic region.


At age 61, Sununu seeks the Republican nomination for the seat being vacated by Democratic Senator Jeanne Shaheen, who defeated him in 2008. This announcement leads to a primary showdown with Scott Brown, a former senator from Massachusetts who has been campaigning since June.


In a video statement, Sununu expressed his surprise and determination: Maybe you’re surprised to hear that I’m running for the Senate again. I’m a bit surprised myself... Somebody has to step up and lower the temperature. Somebody has to get things done.


National Republican leaders view Sununu as a strong candidate who can help the party secure a majority in the Senate come November 2026. The Republican National Committee stated, Sununu’s entrance creates a formidable Republican field poised to make this seat competitive in 2026. Additionally, a super PAC associated with prominent Republican leaders expressed excitement about his candidacy.


The Republicans currently hold a 53-47 advantage in the Senate but face challengers from Democratic candidates in key states, including Ohio, Maine, and North Carolina. The GOP is eyeing New Hampshire as a potential pickup spot that could hinder Democratic efforts to maintain control.


However, Sununu's journey won't be easy; he must first clinch the primary nomination against Brown, who has aligned himself closely with former President Donald Trump. Sununu, who previously criticized Trump, may need to navigate party dynamics carefully.


Despite being out of office for over a decade, Sununu remains a well-known figure due to his family's political legacy; his father served as governor and chief of staff. He aims to address issues such as the economy, healthcare costs, and Social Security if elected.


His likely Democratic opponent, Congressman Chris Pappas, has already initiated a counter-campaign, showcasing the complexity of the upcoming electoral battle as both candidates prepare for the challenges ahead.
