Overview
- Voters on Tuesday delivered clear primary winners for the open New Hampshire Senate seat, nominating Democrat Rep. Chris Pappas and Republican former Sen. John E. Sununu to face each other in the Nov. 3 general election.
- Pappas defeated progressive Karishma Manzur by a wide margin after running as the establishment candidate with endorsements from Sen. Jeanne Shaheen, Sen. Elizabeth Warren, and Vice President Kamala Harris.
- Sununu secured the GOP nomination handily and carried President Donald Trump’s endorsement while drawing on the Sununu family’s deep name recognition in New Hampshire politics.
- In the state’s 1st Congressional District, Stefany Shaheen won the Democratic primary and Trump-backed Anthony DiLorenzo won the Republican primary, producing competitive November matchups as down‑ballot races nationalize.
- The results hand control of the seat significant national weight because Democrats need net pickups to regain the Senate majority, and both parties expect heavy outside spending and national messaging to shape the fall campaign.
