Ryan Fazio's commanding 90.5% position stems from Erin Stewart's abrupt suspension of her campaign days before the Republican state convention, followed by her endorsement of the Greenwich state senator. This shift eliminated the prior frontrunner and consolidated support from party leaders and delegates, positioning Fazio to secure the nomination without a contested primary. His established fundraising, legislative record, and debate appearances have further reinforced trader consensus. Remaining challengers such as Betsy McCaughey would need at least 15% delegate support at the convention to force an August 11 primary, an outcome now viewed as unlikely absent major new developments like unforeseen scandals or shifts in party endorsements.
