In FL-19, the Primary Is the Election

The Race

Florida's 19th congressional district is open for the first time since 2020. Republican Byron Donalds is running for governor rather than seeking a fourth term, and his exit produced the largest congressional field in the state. Ballotpedia counts 12 Republicans and four Democrats on the August 18 primary ballots.

The Republican field includes two former congressmen from other states. Madison Cawthorn represented North Carolina's 11th district before losing his 2022 primary. Chris Collins represented New York's 27th until resigning in 2019 after an insider trading charge, for which President Trump pardoned him in December 2020.

Self-funders Jim Oberweis, a former Illinois state senator and founder of Oberweis Asset Management, and Jim Schwartzel, who owns conservative talk station 92.5 FOX News, lead in cash. Former Trump Commerce Department appointee Catalina Lauf and businesswoman Ola Hawatmeh round out the top tier.

The district itself was substantially redrawn this spring. DeSantis signed a new congressional map on May 4 that reworked 21 of Florida's 28 seats. The 19th district gave up Fort Myers and stretched west across Lee County and inland through Collier, and Collier's elections office confirmed that Naples and Marco Island moved out. Candidates who launched last fall are now running in territory that did not exist when they filed. A voting rights group has sued over the map in Leon Circuit Court.

Ratings

All three major forecasters agree: Cook Political Report rates Florida's 19th Solid Republican, Inside Elections rates it Solid Republican, and Sabato's Crystal Ball rates it Safe Republican.

Cook's partisan voter index for the district is R+14, ranking it the 88th most Republican seat in the country, and Donalds carried it with 66% in 2024. The redraw traded coastal precincts for inland ones that lean at least as far right. Florida Politics' Jacob Ogles wrote that the winner of the Republican primary will be a heavy favorite in November. WGCU noted a blunter fact: a Democrat has never won a congressional election in District 19.

Prediction Markets

Markets give Republicans overwhelming odds of holding the seat in November, so the trading has concentrated on the nomination instead. On Polymarket's FL-19 Republican Primary Winner market, as of Monday, July 27, at 3:35 PM ET, traders put Schwartzel at 40%, Lauf at 21%, and Oberweis at 17%. Cawthorn sits at 3%. These prices move continuously and will have changed by the time you read this.

The market has reversed itself since spring. In April, Polymarket traders made Lauf the clear favorite at roughly 44%, citing her Trump administration résumé and an endorsement from Rep. Anna Paulina Luna. She has since lost more than half that value while Schwartzel, who has poured a reported $1 million of his own money into the race, climbed into the lead.

Total volume across the market is $37,603, thin enough that a few thousand dollars can move a price several points, and the spread between buy and sell prices runs as wide as six cents on the leading contracts.

Experts vs. Markets

Victory Insights found Schwartzel and Oberweis as the only candidates in double-digits in late June, with pollster Ben Galbraith concluding, "54% of voters are undecided. I'll spare you further details, this race is wide open." Three weeks later, Action Solutions put Hawatmeh first at nearly 13%, Collins second at nearly 12%, and Schwartzel third at about 10%, with Oberweis under 5%, Lauf near 4%, and Cawthorn just over 3%.

Polymarket's top three are Schwartzel, Lauf, and Oberweis. The most recent poll's top three are Hawatmeh, Collins, and Schwartzel. Only Schwartzel appears in both. Lauf carries a 21% price on Polymarket and drew under 4% from Action Solutions, a gap of roughly 17 points between what traders believe and what voters told a pollster. Hawatmeh led that poll outright and has no contract on the market at all. Neither does Collins.

What that leaves is a safe Republican seat whose next occupant is genuinely unknown three weeks out. The winner on August 18 will be the heavy favorite in November. But nobody, on either side of this divide, can currently say who that will be.
