Chris Pappas maintains a consistent lead over John E. Sununu in the open New Hampshire Senate race, with recent polling averages showing a 5- to 7-point margin for the Democrat ahead of the November 3 election. Multiple surveys through late October, including Saint Anselm College results of 50-43, reflect stable support for Pappas following earlier periods of tighter margins. Sununu has sought to emphasize independence and distance from national Republican figures while highlighting his prior Senate experience, yet both candidates have seen favorability ratings decline amid heavy negative advertising. The race's positioning aligns with broader state trends favoring Democrats in federal contests despite Republican strength in the gubernatorial matchup. A late surge in Republican turnout or shifts on economic issues could narrow the gap, though current evidence points to structural challenges for the challenger in an open-seat environment.
