Maura Sullivan holds the strongest trader consensus in the New Hampshire 1st District Democratic primary due to her consistent edge in recent polling and a substantial fundraising advantage over the field. The open-seat contest to replace Rep. Chris Pappas has featured heavy spending by Sullivan, a Marine veteran and former Obama administration official, who has outraised Stefany Shaheen and secured endorsements from veterans groups while emphasizing national security and cost-of-living issues. Shaheen, a former Portsmouth councilor and daughter of retiring Sen. Jeanne Shaheen, began with strong name recognition but has trailed in surveys amid negative exchanges over outside donors and healthcare positions. Progressive challengers Carleigh Beriont and others have shown modest support in a fragmented field with significant undecided voters heading into the September 8 vote.
