Byron Donalds secured the Republican nomination in the August 2026 primary with strong backing from former President Trump and Governor Ron DeSantis, while Democrat David Jolly, a former Republican congressman, won his party's contest. Traders assign Donalds an implied 78% probability of victory, reflecting Florida's Republican voter registration advantage, his substantial fundraising lead exceeding $120 million versus Jolly's roughly $15 million, and the party's uninterrupted hold on the governorship since 1999. Recent polling has tightened into a statistical tie or narrow Donalds edge in the final weeks before the November 3 election, prompting some forecasters to shift ratings toward toss-up status amid Jolly's gains with independents. Key variables include turnout among older voters favoring Donalds and crossover support for Jolly on affordability issues.
