Will James Fishback be the Republican nominee for Florida Governor?

Byron Donalds maintains a commanding lead in the August 18, 2026, Florida Republican gubernatorial primary, reflected in trader consensus at 98.6% implied probability. Recent polls show him at 43–50% among likely GOP voters, roughly 30 points ahead of Lt. Gov. Jay Collins, with James Fishback and others in single digits. Key drivers include President Trump’s endorsement, a substantial fundraising advantage exceeding $10 million, and strong name recognition as a sitting U.S. representative. The primary’s proximity leaves limited room for shifts, though late developments such as unexpected endorsements, turnout surges among rival bases, or unforeseen controversies could narrow the gap before ballots close.
