The tight contest for the NH-01 Democratic primary reflects a balance between Stefany Shaheen’s name recognition as the daughter of retiring Sen. Jeanne Shaheen and Maura Sullivan’s stronger fundraising totals, veteran background, and endorsements from groups like VoteVets. Recent Saint Anselm polling shows the two nearly tied in the low-to-mid 20s with substantial undecided voters and multiple other candidates splitting the remainder. Healthcare policy distinctions—ranging from Medicare for All positions to public-option approaches—along with the September 8 primary date and late-cycle campaign activity could still shift support among Democratic primary voters before ballots are cast.
