Incumbent Republican Kat Cammack maintains a commanding lead in Florida’s 3rd congressional district, where nonpartisan ratings classify the seat as Solid or Safe Republican and the Partisan Voter Index stands at R+10. Cammack’s strong 2024 performance, consistent fundraising advantage exceeding $2 million, and automatic advancement through the canceled Republican primary underscore her entrenched position ahead of the November 3 general election. Democratic nominee Seth Harp, who prevailed in the August primary with under 46% of the vote, and independent Mike Klein have raised far less and face structural barriers in a district that has favored Republicans by double-digit margins in recent cycles. The current trader consensus reflects these fundamentals, though late developments such as a major scandal, health event, or unanticipated turnout surge could still alter the outcome before ballots close.
