Maura Sullivan holds a commanding position in the New Hampshire 1st Congressional District Democratic primary due to consistent fundraising dominance, with over $3.3 million raised compared to Stefany Shaheen’s $2.2 million, alongside strong veterans’ endorsements and organizational momentum heading into the September 8 vote. Recent Saint Anselm College polling shows Sullivan narrowly ahead of Shaheen in the low-to-mid 20s, reversing earlier leads for the former Portsmouth councilor and daughter of retiring Sen. Jeanne Shaheen. Negative exchanges over outside donors and policy differences on healthcare have sharpened the contest between the two center-left frontrunners, while Carleigh Beriont’s progressive grassroots push and other challengers remain limited by lower visibility and resources. Traders appear to weigh Sullivan’s resource edge and late polling gains heavily in assessing the outcome.
