Who's In the Race

Rep. Kat Cammack (R-FL) faces Democrat Seth Harp and independent Mike Klein in the Nov. 3 general election in Florida's 3rd District. Florida redrew its congressional district boundaries this year; the Legislature passed the new map April 29, 2026, and it was signed into law May 4. ​

Cammack has represented the district in the U.S. House since 2021 and ran unopposed in the Aug. 18 Republican primary.

Harp is a teacher and talk-show host whose campaign describes him as running to lower costs and hold Cammack accountable. Harp won the Aug. 18 Democratic primary with about 45 percent of the vote over runner-up Tom Wells, who received about 34 percent.

Klein is an Army infantry officer and Gulf War veteran running as an independent.

What They Stand For

Cammack has opposed government regulations she says harm the economy, according to her official House website. She has also supported:

  • Legislation to limit energy regulations and rules she argues would raise costs,
  • Rural power-grid investment and reliable electricity access; and
  • a record of serving on Ted Yoho's staff for nearly a decade before she entered Congress.

Harp has proposed the H.E.A.R.T. Act, which would tax large-scale corporate home purchases and incentivize construction of affordable housing, according to his campaign website. He has also proposed:

  • The D.O. Initiative to double the behavioral-health workforce over a decade through tuition assistance, scholarships and workforce grants; and
  • holding Cammack accountable.

Klein has identified protection of constitutional rights as one of his campaign's five central pillars, according to his campaign website.

The Money Behind the Race

Through July 29, Cammack had raised about $2 million and had about $877,000 in cash on hand, while Harp had raised about $38,000 and had about $3,000 on hand, giving Cammack roughly 290 times as much cash. Independent Klein had raised about $59,000 through June 30 and had about $18,000 on hand, while his $25,000 in debt equaled about 42 percent of his total receipts.

Outside groups have spent about $31,000 supporting Cammack, all of it from Latinos for Conservative Values.
