Democratic Representative Chris Pappas leads the open-seat race for New Hampshire’s U.S. Senate seat after incumbent Jeanne Shaheen announced her retirement. Recent polls show Pappas ahead in the Democratic primary and holding double-digit or closer leads against likely Republican nominees such as John Sununu in general-election matchups. New Hampshire’s partisan lean, Democratic performance in recent federal contests, and Pappas’s established statewide profile contribute to the strong trader consensus favoring the Democratic nominee at 89.5 percent. The September 8 primaries and November 3 general election remain the key upcoming milestones that could shift probabilities if turnout patterns or late developments alter the current landscape.
