Senate Primary Dynamics
The Republican Senate primary features former Sen. John Sununu, who has received the endorsement of Donald Trump, Senate Majority Leader John Thune, and the National Republican Senatorial Committee. Sununu is competing against former Sen. Scott Brown, who previously served as a U.S. ambassador. On the Democratic side, Rep. Chris Pappas is seeking his party's nomination but faces a challenge from Karishma Manzur, a scientist and member of the Democratic Socialists of America who advocates for "Medicare for All."
House District Contests
In the 1st District, which includes Manchester, a crowded field is competing for the seat previously held by Pappas. Establishment-aligned Democratic candidates include Marine veteran Maura Sullivan and former Portsmouth City councilwoman Stefany Shaheen. Progressive candidates Christian Urrutia and Carleigh Beriont are also running. The Republican primary for the same seat features businessman Anthony DiLorenzo, who is backed by Trump, alongside state Rep. Brian Cole and CEO Hollie Noveletsky. In the state's other congressional district, Democratic Rep. Maggie Goodlander faces a primary challenge from state Rep. Paige Beauchemin. Beauchemin, who is running on a progressive platform, has raised $44,000 compared to Goodlander’s $4.2 million.
