The open seat created by incumbent Democrat Chris Pappas's retirement to run for Senate has positioned New Hampshire's 1st Congressional District as a contest where Democratic primary frontrunners like Stefany Shaheen maintain strong polling leads while Republicans face a fragmented field. Recent University of New Hampshire and Saint Anselm surveys show Shaheen ahead in the September primary, supported by robust early fundraising from candidates including Maura Sullivan. Cook Political Report rates the race Likely Democratic, reflecting the district's D+2 partisan voting index and its narrow 2024 presidential margin. These factors reinforce trader consensus on Democratic retention ahead of the general election, though Republican primary outcomes and national midterm dynamics could still influence the final result.
