Byron Donalds Wins Florida Republican Governor Primary on August 18

On Tuesday, August 18, 2026, U.S. Rep. Byron Donalds won the Republican primary for Florida governor, defeating Lt. Gov. Jay Collins and a crowded field of GOP challengers to become the party’s nominee to succeed term-limited Gov. Ron DeSantis. The Associated Press called the race shortly after polls closed statewide at 8 p.m. ET, projecting Donalds the winner as returns rolled in from across Florida.

Donalds will face David Jolly, who won the Democratic gubernatorial primary the same night, in the November 3 general election for control of the nation’s third-largest state.

Editor’s note: This article draws on reporting from the Associated Press, CBS News, NBC News, WFTV, and the Tallahassee Democrat as of August 18–19, 2026. Vote totals may shift as counties finalize canvassing.

Primary results

With most expected votes counted by late evening, Donalds led the Republican field by a wide margin and avoided a runoff.

Candidate	Role	Approx. share
Byron Donalds	U.S. representative (Southwest Florida)	~48–49%
Jay Collins	Lieutenant governor	~25%
James Fishback	Political newcomer	~10%
Paul Renner	Former House speaker	~8%

Donalds carried roughly half of the Republican electorate while Collins, DeSantis’s 2022 running mate, finished a distant second. Fishback, a conservative online figure whose campaign drew scrutiny for inflammatory rhetoric and fringe endorsements, and Renner, who had led the Florida House, split the remainder.

Who is Byron Donalds?

• First elected to Congress in 2020, representing Naples, Fort Myers, and surrounding communities in Florida’s 19th District
• Prominent House Freedom Caucus member who challenged Kevin McCarthy during the 2023 speaker fight, forcing multiple rounds of voting
• Brands himself as a MAGA lawmaker aligned with President Donald Trump, who endorsed Donalds in May 2026
• Would be Florida’s first Black governor if elected in November
• Campaign framed around continuing DeSantis-era conservative governance — lower taxes, border security, and what he calls defending the “Florida Dream”

Before Congress, Donalds worked in banking and served on the Naples City Council. He rose quickly in national Republican politics as a vocal Trump ally and frequent cable-news presence.

How Donalds won the Republican primary

Fundraising and organization

Donalds entered the primary with a commanding financial advantage. NBC News reported he raised roughly $100 million, while the Tallahassee Democrat cited a $111 million war chest that dwarfed his rivals. That spending power fueled statewide advertising, field operations, and a professional campaign apparatus that Collins and Renner struggled to match.

Trump’s endorsement

Trump’s backing proved decisive in a state he has treated as a political home base since leaving the White House. Donalds campaigned heavily on the endorsement, appearing at rallies and framing himself as the candidate who could carry Trump’s agenda into the governor’s office.

Collins, Renner, and Fishback each pitched themselves as heirs to DeSantis’s legacy, but none broke through against Donalds’s combination of money, name recognition, and presidential support.

A united party message

In a statement posted on social media after the AP call, Donalds thanked supporters and urged Republicans to unite for the general election:

I am grateful to my family, my team, my volunteers, and every Floridian who powered us to this victory. Now is the time for the Republican Party to unite. By working together, we can make Florida more affordable and defend the Florida Dream for our families, seniors, and young people.

Why the governor’s seat is open

Florida law limits governors to two consecutive terms. DeSantis, elected in 2018 and reelected in 2022, cannot seek a third straight term in 2026. His departure opened one of the most watched Republican primaries of the midterm cycle.

DeSantis did not endorse a successor in the primary, leaving Collins, Renner, and Donalds to compete for the mantle of his conservative governing style. Donalds’s victory positions him as the standard-bearer for both the DeSantis and Trump wings of Florida Republicans.

The November matchup

On the Democratic side, David Jolly — a former Republican congressman who left the GOP in 2018 and became a prominent Trump critic — won his party’s primary with roughly 61% of the vote. Jolly is running with former Rep. Gwen Graham on Florida’s joint governor–lieutenant governor ticket.

General election date	November 3, 2026
Cook Political Report rating	Solid R — Donalds is the favorite
July polling	James Madison Institute poll showed Donalds leading Jolly 45% to 38% among likely voters
State trend	Florida has moved sharply Republican in presidential and statewide races since 2016

Jolly pitches himself as a centrist who can appeal beyond the Democratic base, but he faces the same structural challenge that sank former Republican Gov. Charlie Crist when Democrats nominated him in 2022 — DeSantis won that race by nearly 20 points.

What the win means for Florida politics

Donalds’s nomination consolidates Republican control of Florida’s top-ticket branding heading into November. His Freedom Caucus credentials and Trump alignment signal continuity with the party’s current national direction, while his potential history-making role as Florida’s first Black governor adds a new dimension to the fall campaign.

For Democrats, Jolly’s nomination keeps the focus on Trump fatigue and affordability — housing costs, insurance premiums, and the cost of living have been central themes in both parties’ messaging. Whether a party-switching moderate can close the gap in a state that Trump carried in 2024 remains the central question of the general election.

National Republicans will also watch how Donalds performs as a governor candidate with strong ties to the House’s most conservative bloc — a profile that energizes the base but can complicate outreach to suburban swing voters.

Discussion

Donalds’s primary win was built on money, Trump’s endorsement, and a Republican electorate that still leans heavily toward the MAGA wing in statewide races.

1. Does Byron Donalds need to distance himself from Trump to win suburban voters in November, or is full alignment still the winning formula in Florida?

The state has trended Republican for a decade, but general-election electorates are broader than primary ones. How much room does Donalds have to moderate his message without losing the base that powered Tuesday’s win?

2. Can Jay Collins’s 25% showing signal a lane for Republicans who preferred a DeSantis-style candidate without Donalds’s House Freedom Caucus profile?

Collins fell short, but he was the runner-up. Does that bloc consolidate behind Donalds in November, or does some of it stay home?
