Incumbent Sen. Jeanne Shaheen's retirement has opened New Hampshire's Senate seat, but trader consensus prices a Democratic victory at 81.5% implied probability, reflecting Rep. Chris Pappas's dominance in Democratic primary polls (61% in April University of New Hampshire survey) and narrow general election leads over GOP frontrunner former Sen. John Sununu (49%-42% in that poll). Recent fundraising reports show Pappas holding a cash advantage, bolstering his path in this battleground state where Democrats have held both Senate seats since 2017. The GOP primary remains crowded with Sununu leading Scott Brown, potentially leading to a bruising contest ahead of the September 8 primaries, while national headwinds like high gas prices highlight Pappas's gas tax suspension bill. Odds diverge from some statistical ties in earlier Emerson polling, underscoring bettors' emphasis on Pappas's incumbency-like popularity and historical base rates favoring Democrats in NH federal races.
