Marcus Carter leads the Florida 9th Congressional District Republican primary at 45.5 percent amid a five-candidate field for the open seat on August 18. His recent endorsement from the American Patriot Executive Committee has consolidated support in the absence of public polling, while Thomas Chalifoux at 29.5 percent draws strength from dominant fundraising that exceeds $2.3 million with substantial cash reserves and a recent pledge of $3 million in personal funds. Justin Story at 26 percent benefits from his military background as a former F-18 pilot, though the remaining candidates trail with under 8 percent each. Traders price the outcome based on endorsements, internal surveys, and campaign resources ahead of the primary in this competitive Republican contest.
