Byron Donalds dominates GOP field days before Florida governor primary
Florida Governor Republican Primary Winner
Polymarket prices this Byron Donalds at 99%. The reporting broadly agrees.
Florida Republicans head to the polls August 18 to pick their nominee for governor, and Congressman Byron Donalds enters the final stretch as the dominant front-runner. A Florida Politics survey released last week put Donalds 31 points ahead of his nearest GOP rival, with former Rep. David Jolly — running on the Democratic side — leading a separate primary field. The Orlando Sentinel corroborated that Donalds tops the Republican ballot while Jolly leads the Democrats. Miami Herald reporting noted that former House Speaker Paul Renner has gone on the offensive in the closing weeks, targeting both Donalds and Dr. Anthony Fauci. With the primary just days away, traders put Donalds at 99%, which aligns with the double-digit polling lead the surveys show. The winner advances to November's general election to succeed term-limited Governor Ron DeSantis.
Background
Donalds, 46, is a three-term congressman from Southwest Florida who has built a national profile as a MAGA-aligned conservative and frequent surrogate for Donald Trump. He launched his gubernatorial bid in 2025, quickly consolidating grassroots and establishment support in a state where Trump's endorsement machinery still carries significant weight. His main Republican rival, Paul Renner, served as Speaker of the Florida House and has emphasized his legislative record on crime, immigration, and education. The GOP primary winner will face the Democratic nominee — likely David Jolly, a former Republican congressman turned critic of his old party — in a November general election to replace DeSantis, who is term-limited. Florida has trended sharply Republican in recent cycles, with the GOP holding every statewide elected office. The market resolves on the first official announcement of results from the Florida Republican Party, with August 18 as the primary date.
The precedent
- Ron DeSantis won the 2018 Florida Republican gubernatorial primary with about 57% of the vote, defeating Adam Putnam by roughly 20 points after receiving Donald Trump's endorsement.
- Florida governors are limited to two consecutive four-year terms under the state constitution, meaning DeSantis cannot seek re-election in 2026.
- No Democrat has won a Florida gubernatorial election since Lawton Chiles was re-elected in 1994.

- David Jolly leads the Democratic primary field for Florida governor.
- The Florida gubernatorial primary is scheduled for August 18, 2026.

How outlets frame it
- Miami Herald: Emphasizes the combative closing stretch, spotlighting Renner's attacks on both Donalds and Fauci — framing the primary's final phase as more contentious than the polling gap might suggest.
What to watch
Polls close across Florida's panhandle at 8 p.m. Eastern on August 18, with results expected to roll in through the evening. Watch Renner's final-weeks attacks on Donalds — covered by the Miami Herald — for any late erosion in the congressman's lead, and whether turnout in Donalds' Southwest Florida base meets expectations. The first official call from the Florida Republican Party will trigger resolution of this market.
