Recent polling averages showing Chris Pappas maintaining a 5- to 7-point lead over John E. Sununu in the final weeks have anchored trader consensus for the open New Hampshire Senate seat. The Democratic congressman has consolidated support among independents and undeclared voters following the September primaries, while negative advertising has depressed favorability for both nominees. Sununu’s name recognition from prior Senate service and Republican outside spending have not yet narrowed the gap in surveys conducted through mid-October. With the November 3 general election approaching, traders appear to view Pappas’s consistent edge and fundraising lead as durable, though a late surge in Republican turnout or shifts among the state’s large independent bloc could still alter the outcome.
