Stefany Shaheen secured the Democratic nomination for New Hampshire’s 1st congressional district in the September 8 primary, positioning her as the clear favorite against Republican nominee Anthony DiLorenzo. The open seat, previously held by Rep. Chris Pappas, sits in a district rated Lean or Likely Democratic by major forecasters due to its recent voting patterns and southeastern New Hampshire demographics. Shaheen benefits from strong name recognition as the daughter of retiring Sen. Jeanne Shaheen, along with a consolidated party base following a competitive primary. DiLorenzo, a businessman backed by President Trump, consolidated Republican support but faces structural headwinds in a district where Democrats have held the seat for most of the past two decades. These dynamics underpin trader pricing that heavily favors the Democratic nominee heading into the November general election.
