Incumbent Kelly Ayotte maintains a commanding position in the New Hampshire Republican gubernatorial primary due to her strong approval ratings and absence of any declared major challengers ahead of the September 8, 2026, vote. Recent polling from the University of New Hampshire and Saint Anselm College shows her leading potential Democratic opponents by double-digit margins in the general election, underscoring broad GOP support and her alignment with the moderate governance approach associated with prior Republican administrations. Speculation about a primary bid by Trump-aligned figure Corey Lewandowski emerged in late 2025 over redistricting disputes but has produced no formal candidacy or sustained momentum since, leaving traders to price in Ayotte's structural advantages as incumbent with limited risk of an upset.
