Chris Pappas maintains a commanding lead in New Hampshire’s Democratic U.S. Senate primary due to his established record as a two-term representative, superior fundraising exceeding $13 million compared to Karishma Manzur’s roughly $200,000, and consistent polling advantages of around 59 percent to her 20 percent in June surveys. Manzur’s challenge from the left, centered on criticisms of pro-Israel campaign contributions and calls to restrict super PACs, has narrowed the gap among younger and progressive voters but has not overcome Pappas’s broader support among Democratic primary voters. With the September 8 primary approaching, trader consensus reflects Pappas’s institutional backing and name recognition in an open-seat contest. A late surge by Manzur could occur through stronger debate performances or shifts in turnout among specific voting blocs, though such movement remains limited by the resource disparity and short timeline remaining.
