Trader consensus on Polymarket heavily favors Raymond McKay (85%) as the Republican nominee in Rhode Island's U.S. Senate primary, reflecting his commanding lead in recent internal polls and superior fundraising totals exceeding $500,000. McKay, a former state representative, benefits from endorsements by key GOP figures including former Governor Donald Carcieri and strong grassroots support in a low-turnout primary expected September 10. Challenger Allen Waters (8.8%) trails due to limited visibility and weaker organization, though his military background appeals to a niche conservative base. No major shifts reported since August polls solidified McKay's dominance, with minimal undecideds (under 5%) limiting upside for others amid Rhode Island's reliably Democratic general election lean.
