John E. Sununu maintains overwhelming trader consensus in the New Hampshire Republican Senate primary due to consistent double-digit leads in recent surveys, including University of New Hampshire and Saint Anselm College polls showing him ahead of Scott Brown by 30 points or more ahead of the September 8 vote. His position stems from the Sununu family’s established role in state politics, prior service in the U.S. Senate representing New Hampshire, stronger fundraising totals, and an endorsement from President Trump. Brown, a former Massachusetts senator and ambassador with limited recent New Hampshire electoral success, has not narrowed the gap despite his campaign efforts. Withdrawn candidates such as Dan Innis have endorsed Sununu, leaving negligible support for remaining minor contenders. Scenarios that could still shift the outcome include an unexpected late scandal or sharply depressed turnout, though current polling and campaign dynamics point to a decisive result.
