Donalds heads GOP primary to succeed DeSantis as Florida governor

Florida Republicans cast their primary ballots on August 18, 2026, to pick a nominee to succeed term-limited Governor Ron DeSantis, with U.S. Representative Byron Donalds entering the vote as the clear front-runner. Donalds, a Naples-area congressman who built his national profile as a Black conservative and through close loyalty to President Trump, led the GOP field by roughly 31 points in the final polling window, according to a Florida Politics survey. NBC News and El País both framed the contest as effectively settled on the Republican side, with Donalds already pivoting toward a general-election matchup against Democrat David Jolly. The specific question at issue is whether Donalds finishes with a margin of victory between 20 and 25 percentage points over his nearest Republican competitor — a band that 96% suggests is the most likely single outcome, though the final polls pointed to a wider gap.

Background

Donalds rose through Florida Republican politics as a state lawmaker before winning a House seat anchored in Fort Myers, a district where he fended off a crowded primary field. His congressional career has been defined by MAGA alignment; the New York Times noted that his loyalty to Trump, more than any single legislative achievement, propelled him into the governor's race. He now faces the task of replacing DeSantis, who leaves office after two terms that reshaped Florida's policy landscape on education, immigration, and pandemic response. The Democratic side features Jolly, a former Republican congressman turned Democrat, whom ABC News described as mounting an improbable bid to prove the party can still compete in a state that has trended red. The primary's margin of victory — specifically whether Donalds wins by 20 to 25 percent — is the proposition being resolved.

The precedent

• Ron DeSantis won the 2018 Republican gubernatorial primary by approximately 20 percentage points over Adam Putnam after a late Trump endorsement reshaped the race.
• No Florida governor has won a third consecutive term since the state's two-term limit was enacted; DeSantis is term-limited after winning re-election in 2022.
• Florida's Republican primary for governor is closed, meaning only registered Republicans can vote, which typically produces a smaller and more conservative electorate than the general election.

What to watch

Primary results will be reported the evening of August 18, with Florida polls closing at 7 p.m. Eastern. Watch the margin between Donalds and the second-place Republican finisher as returns come in from the Panhandle through South Florida; the final gap determines whether the 20–25 percent band holds. A wider or narrower victory would shift attention to how Donalds consolidates GOP support before facing Jolly in November.
