3 candidates · ballot order · Kat Cammack currently holds this seat
Medium confidenceMedium confidenceThe candidate's stated positions and basic record are documented, but coverage is thin — often little independent reporting, or criticism from only one side.What would raise it: More independent reporting, a documented voting record, or published criticism from a named opponent would raise this.
What they say they stand for
Their own words. Claims, not verified facts.
Securing the southern border.
Low taxes and restrained federal spending; she describes herself as a budget hawk.
Second Amendment rights.
Support for small businesses.
Support for veterans and first responders.
Election integrity measures including voter identification.
What they’ve actually done
Documented record from official sources.
U.S. Representative for the 3rd District since January 2021; re-elected in 2024 with 61.6%.
Civilian graduate of the United States Naval War College.
Advanced from the August 18, 2026 Republican primary.
Arguments in favor
She votes the conservative position almost without exception — Heritage Action scores her at 96% across both the 117th and 119th Congresses — so voters in a Republican district know what they are getting.
— Heritage Action legislative scorecard
After nearly dying from an ectopic pregnancy she legislated on the problem rather than dropping it, introducing the TRUTH in Women's Healthcare Act: "No woman facing a medical emergency like a miscarriage or ectopic pregnancy should be left in danger because of confusion or misinformation... the public is properly informed on what current law does — and does not — allow."
— Kat Cammack, on introducing the resolution
Arguments against
The delay in her own emergency care was caused by the abortion ban she supports, not by its critics: "Rep. Kat Cammack's ectopic pregnancy put her life at risk, and her treatment was delayed because of the very abortion ban she supported."
— Alachua County Democratic Party
Blaming advocates for the confusion misplaces the fault: "These laws are deliberately vague, creating a climate of fear and confusion among doctors who face prison time, fines, and the loss of their medical licenses for doing their jobs. That's not a messaging problem — it's a legislative failure."
— Keisha Mulfort, ACLU of Florida, quoted by Newsweek. Cammack's own account, given to the Wall Street Journal, calls the episode "absolute fearmongering at its worst" by activists; Florida's law does treat ectopic pregnancy as an emergency rather than an abortion
What we couldn’t verify
Her committee assignments were not established from the sources found.
No Democratic Congressional Campaign Committee page about her by name was found; the criticism above comes from the county party and from national coverage of the ectopic-pregnancy story rather than from her opponent's campaign.
He would be an accessible member in a district whose incumbent he says is not: he publicly challenged Cammack to co-host a joint FL-03 town hall — "It's been 72 hours since I cordially challenged @Kat_Cammack to Co-Host a joint FL-03 Town Hall" — and got no answer.
— Seth Harp, reported by The Floridian
A sixth-grade civics teacher and Gainesville broadcaster, he is running on lowering costs and on protecting Social Security, Medicare and Medicaid as programmes people have already paid for, and on the principle that government should "work for working people".
— Seth Harp's campaign
Arguments against
He is not running a real campaign: "You aren't a serious candidate, Seth, and you're just a sad clown trying to pull a political stunt." He had failed to file his personal financial disclosure report and his Q1 and Q2 FEC reports.
— Derek Dufresne, Kat Cammack's chief strategist, reported by The Floridian
The town-hall challenge was theatre aimed at a member who was in Washington doing the job she was elected to do.
— Alachua County Republicans, reported by The Floridian
What we couldn’t verify
He has held no elected office, so there is no voting record to set against his campaign's positions.
Whether the disclosure and FEC filings Cammack's strategist named were subsequently made was not established from the sources found.
His positions on immigration, foreign policy and taxation were not stated in material available.
Getting money out of politics so that, as he puts it, the voices of the many outweigh the greed of the few; he treats this as a precondition for other policy.
Defending democratic institutions, one of the five pillars his campaign names.
An agenda he calls American Dream 2.0, aimed at economic hardship in north Florida.
Independence from party organisations, corporate political action committees and special interests.
What they’ve actually done
Documented record from official sources.
Fifth-generation Floridian, raised in Gainesville.
Military veteran; took the oath to defend the Constitution at 17.
Qualified as a no-party-affiliation candidate for the November 3, 2026 general election.
Has not held elected office.
Arguments in favor
We found none published about this candidate in the sources reviewed.
Arguments against
We found none published about this candidate in the sources reviewed.
What we couldn’t verify
No published criticism of Klein by name could be found, from either major-party campaign or from news coverage, and no published case for him beyond his own campaign site. As a candidate with no party organisation behind him he has drawn very little coverage. Because no case against him exists on the record, none is presented for him either, rather than showing his own campaign's case unanswered.
His fundraising and any endorsements were not reported in material available.

Florida held its primary on August 18, 2026. Three candidates are on the November ballot: Republican incumbent Kat Cammack, Democrat Seth Harp and Mike Klein, running with no party affiliation. Florida enacted a new congressional map in May 2026, but districts 1 through 7 were left unchanged; this one covers north central Florida including Gainesville. Roster from the Florida qualifying lists as reported by Politics1 and Wikipedia. Arguments are shown for Cammack and Harp, who have criticised each other on the record. Mike Klein has drawn no published criticism by name and no published case for him beyond his own site, so neither column is filled for him; his positions are in his profile.
This is one contest on a longer ballot
A Florida ballot also carries state legislative districts, county offices, judicial seats and often local questions — and which of them you vote on is decided by your street address, not your city or ZIP code.
