Raymond McKay commands 87.5% trader consensus as the likely winner of Rhode Island's Republican U.S. Senate primary on September 8, reflecting his dominant position in a low-turnout contest against perennial candidate Allen Waters (2.1%), who has repeatedly underperformed in past races, including the 2020 Senate bid where state Republicans disavowed him amid weak fundraising and vote shares. No significant developments—such as endorsements, polls, withdrawals, or new entrants—have occurred in the past 30 days, solidifying McKay's frontrunner status based on superior organization and name recognition in this deep-blue state. Late-breaking endorsements or turnout surges could narrow the gap, though structural advantages favor McKay.
