Core Event: Donalds Leads Republican Primary Ahead of August 18 Vote
Florida voters will choose the Republican nominee for governor on Tuesday, August 18. Congressman Byron Donalds—the Trump-backed candidate from Naples—has entered the contest as the overwhelming favorite. Prediction-market odds on Kalshi and Polymarket placed Donalds at a 98-99 percent chance of winning, and every major poll in the weeks before the primary shows him leading Lieutenant Governor Jay Collins by double-digit margins.
Background & Context
The race unfolds in a state where Governor Ron DeSantis is term-limited, and a rivalry between DeSantis and former President Donald Trump shapes the GOP field. Trump endorsed Donalds in February 2024, a move observers called a “golden ticket.” The primary also follows the adoption of a new congressional map designed to boost Republican prospects in the November midterms.
Data & Statistics
- Fundraising: Donalds raised roughly $10 million in the most recent quarter; each opponent raised well under $1 million.
- Endorsements: Trump, former U.S. Senator Rick Scott, Agriculture Commissioner Wilton Simpson, and the full Florida Cabinet.
- Polls:
- July 14-16 (Fabrizio Lee): Donalds 53 % vs. Collins 10 % (43-point spread).
- July 21-22 (The Political Matrix & The Listener Group): Donalds 32 %; Paul Renner 19 %; James Fishback 13 % (32 % undecided).
- July 20-26 (Targoz Market Research): Donalds 49 % vs. Collins 18 % (31-point margin).
- July 27-29 (Quantus Insights): Donalds 50 % vs. Collins 16 % (34-point margin).
- August 10 (Fabrizio Lee): Donalds 54 %.
- Voter Registration (July 20): About 13.5 million registered voters; 5.6 million (42 %) Republicans, 4.1 million (30 %) Democrats, and 3.3 million (25 %) unaffiliated.
Official Statements & Responses
- Endorsements: Trump’s endorsement and those of Scott, Simpson, and the Cabinet were announced through campaign releases.
- Department of Justice: After James Fishback alleged that Donalds was under a federal investigation, the DOJ publicly denied the claim.
Criticism & Opposition
- Fishback’s Accusation: Businessman James Fishback claimed Donalds was under a federal investigation without evidence; the DOJ’s denial serves as the official rebuttal.
- Collins’ Counterpoint: Collins positioned himself as the underdog, suggesting that Donalds’ financial lead does not guarantee voter support.
Conflicting Reports & Gaps
Polls show Donalds’ support ranging from 32 % (July 21-22 Political Matrix) to 54 % (August 10 Fabrizio Lee). Differences in methodology, sample size, and timing create uncertainty about the exact size of his lead as the primary approaches.

What’s Next
Early voting began on August 3, 2026, with more than 1.3 million ballots cast by mid-day on primary day. The Associated Press will report results after polls close at 7 p.m. local time and will declare a winner only when the margin exceeds the 0.5 % threshold that would trigger a machine recount. The outcome will determine the GOP nominee who will face Democratic nominee David Jolly in the November general election.
