John E. Sununu is a New Hampshire Republican and former U.S. Representative (1997–2003) and Senator (2003–2009); son of Gov. John H. Sununu. In 2026, he seeks to reclaim his Senate seat.
In New Hampshire, Democrats have channeled support behind Rep. Chris Pappas, while Republicans rally behind former Sen. John Sununu. The contest for the state’s Senate seat is part of a broader national battle for control of Congress, with both parties aiming to influence the Senate in November. Primary results and endorsements have shaped the field, as Sununu and Pappas gain or lose ground amid ongoing scrutiny of national politics.
Developing contests across the U.S. see heavy spending from national committees and super PACs. Texas, North Carolina, Ohio, Iowa, and Kansas are among the states where ads and funding shifts aim to influence close races. The dynamic spending reflects a broader scramble to protect or seize Senate control as Election Day approaches.
