Stefany Shaheen leads trader consensus in the New Hampshire 1st Congressional District Democratic primary at 63 percent, buoyed by her name recognition as the daughter of retiring U.S. Senator Jeanne Shaheen, prior service on the Portsmouth city council, and recent local endorsements including multiple mayors and Teamsters Local 633. Multiple candidate forums in late May emphasized shared opposition to federal policy changes, yet Shaheen’s institutional support and fundraising totals exceeding $1.8 million have widened her edge over Maura Sullivan at 24 percent. Sullivan, a Marine Corps veteran and former Obama administration official who ran for the seat in 2018, maintains competitive fundraising and party roles but trails in visibility. Carleigh Beriont and Heath Howard remain at low single digits with limited recent campaign activity ahead of the September 8 primary.
