Scott Singer leads the Florida 25th Congressional District Republican primary field as the clear frontrunner, backed by name recognition as former Boca Raton mayor and a late-July GOP poll showing him at 21% support among likely primary voters compared with lower single digits or teens for rivals Dan Franzese and George Moraitis. Traders price the August 18 contest accordingly, reflecting Singer’s advantages in local endorsements, fundraising visibility, and platform emphasis on affordability, taxes, insurance reform, and border security. The other listed candidates trail sharply, consistent with limited polling and campaign reach, while a joint lawsuit by Singer, Franzese, Moraitis, and the state party seeks to remove a Libertarian competitor and consolidate the November ballot. With the primary one day away, these positioning factors explain the current market consensus.
