Helena Foulkes leads trader consensus at 73.5% implied probability to win Rhode Island's Democratic gubernatorial primary on September 8, driven by consistent polling advantages over incumbent Governor Dan McKee, including a February University of New Hampshire survey showing her at 34% to his 18% among likely voters, with 41% undecided. McKee's low approval ratings around 20% and trailing fundraising have eroded his incumbency edge, while Foulkes benefits from endorsements like Attorney General Peter Neronha's in March. Recent agreement to three primary debates underscores the contest's competitiveness ahead of early voting in late August, positioning longshots Gregory Stevens at 5.7% per his polling share and former Speaker Joe Shekarchi at 2.2% despite his February withdrawal.
