Republican Rep. Kat Cammack won re-election to represent Florida's 3rd Congressional District, beating Democrat Seth Harp by 10.2 percentage points. Independent Mike Klein received 1.8% of the vote.

Why it matters

The result extends Cammack's hold on a seat she has occupied since 2021 and reflects the margins she has posted in recent cycles. Voters across Florida's 3rd District, which spans Alachua County and 11 other counties in north central Florida, chose continuity in the House delegation.

Cammack's most recent campaign raised just shy of $2.5 million and spent about $2 million, while Harp raised about $170,000 and spent about $130,000, according to Federal Election Commission filings. The extraction does not address how these totals compare with the 2024, 2022 or 2020 campaigns.

The details

Cammack, who has held the seat since 2021, faced Democrat Seth Harp and independent Mike Klein. Klein's support, according to the extraction, drew from voters across party lines by focusing on serious issues and maintaining a respectful tone.

2023: The Biden administration issued a rule defining rifles, which Cammack opposed.

Political Context

Cammack's 2026 margin of 10.2 points falls short of the at-least-15-point victories she recorded in 2020, 2022 and 2024. The extraction does not describe the specific policy arguments raised by Harp or Klein during the campaign.

Florida's 3rd District voters now have Cammack continuing to represent them in the House for another term. The extraction does not describe any new rules or funding changes that would directly affect residents' daily lives.

The takeaway

Cammack's re-election keeps Florida's 3rd District seat in Republican hands while showing a narrower margin than her earlier wins. Readers tracking congressional races can compare future results against these figures to judge whether the district's competitiveness is changing.
