Raymond McKay holds a commanding lead in Rhode Island’s Republican U.S. Senate primary, scheduled for early September 2026, reflecting his stronger fundraising totals, established party infrastructure, and prior candidacy experience against Democratic incumbent Jack Reed. The state Republican convention endorsed McKay in June 2026, underscoring organizational backing that Allen Waters lacks; Waters, who ran in prior cycles, shows negligible recent campaign activity or resources and has not secured ballot placement in some reporting. Traders price this outcome based on these structural advantages heading into a low-turnout primary. A late withdrawal by McKay or an unforeseen eligibility ruling could still alter the result before votes are cast.
