The Oklahoma City-based cybersecurity executive challenged Republican incumbent Stephanie Bice and lost the November 5, 2024, general election, 60.69% to 39.31%.
Horn’s campaign used her experience in critical-infrastructure security, privacy, energy-sector cybersecurity and executive leadership as an argument for bringing technical expertise to Congress. The word “vet” in descriptions of her should be understood as professional experience; the available biographies do not establish that she is a military veteran.

Who Madison Horn is
Horn is an Oklahoma City-based cybersecurity executive, a seventh-generation Oklahoman and a citizen of the Cherokee Nation. Candidate profiles describe her as the founder and CEO of RoseRock Advisory Group, with work spanning cybersecurity consulting, privacy, critical infrastructure, energy security and executive strategy. Her professional history is associated with Siemens Energy, PwC, Accenture, FusionX and Securicon, according to BallotReady and CAIR Oklahoma’s candidate profile.
Her personal biography emphasizes rural Oklahoma roots, work on a family farm and several early jobs before moving into a technical career and corporate leadership. That combination—local identity and experience with multinational organizations—was central to the campaign’s case that she could translate Oklahoma concerns into national policy.
#1 Best Overall
Madison Horn is not Kendra Horn, the former Oklahoma congresswoman. They are different people.
What “cybersecurity vet” means in her case
“Cybersecurity vet” can mean an experienced practitioner, but it can also suggest military service. The sources for Horn establish a long cybersecurity career, not military-veteran status. “Cybersecurity executive” or “cybersecurity professional” is therefore the more precise description.
What office she sought
Horn sought a seat in the U.S. House representing Oklahoma’s 5th Congressional District, a central Oklahoma and Oklahoma City-area district. The Federal Election Commission identifies her as the Democratic candidate and lists her authorized committee as Oklahomans for Madison (candidate ID H4OK05199). Her public announcement described a challenge to Republican incumbent Stephanie Bice, and a later post said she was officially on the ballot:

Horn had previously run as a Democrat for the U.S. Senate in 2022 and lost the general election to Republican James Lankford, according to the FEC’s 2022 federal election results.
Why cybersecurity became a campaign credential
Horn’s professional background covered ethical hacking, breach response, threat and risk management, security strategy, cybertechnology, critical-infrastructure protection and energy-sector security. A CAIR Oklahoma profile describes that experience; her own campaign materials also discuss protecting infrastructure and the energy sector from terrorist organizations and other threats.
Her argument was not that technical experience automatically produces better legislation. It was that lawmakers making decisions about national security, privacy, economic infrastructure and democratic institutions should understand the systems and risks involved. Cybersecurity can touch several congressional responsibilities:
Rank #3
- Critical infrastructure: electricity, pipelines, water systems, health care and communications depend on increasingly connected technology.
- Energy security: cyber incidents can create operational and economic consequences beyond a single company.
- Privacy and data protection: policy choices affect how businesses and government agencies collect and secure personal information.
- National security: cyber threats involve criminal groups, state-backed actors and attacks on public institutions.
- Workforce development: technical training can support both cybersecurity readiness and higher-skilled employment.
The available profiles describe broad priorities rather than a detailed legislative program. They do not establish specific bill language, funding levels, enforcement mechanisms or a documented congressional record.
Her broader policy message
Horn presented the race as a response to what she said were failures to address national-security and economic pressures, restore trust and make government work more effectively. She also argued that private-sector and technical experience could improve policymaking. Candidate and voter-guide materials identify these additional priorities:
- Border security and immigration-system reform.
- Responding to the fentanyl crisis.
- Protecting reproductive freedoms.
- Senior citizens and social programs.
- Vocational and technology training.
- Rural broadband and economic development.
- Firearm restrictions focused on people who commit or threaten violence.
- Veterans’ health care and transition services.
- Small businesses and emerging industries.
These descriptions are issue positions and themes, not necessarily complete implementation plans. The profiles generally do not specify how each proposal would be financed, which federal agency would administer it or what legislation would carry it.
The 2024 contest against Stephanie Bice
Horn’s Democratic campaign faced Bice, the Republican incumbent, in a state and district with a strong Republican baseline. That partisan environment is important context, but the available election data cannot show whether cybersecurity helped or hurt Horn with voters.
Certified general-election result
| Candidate | Party | Votes | Share |
|---|---|---|---|
| Stephanie Bice | Republican | 207,636 | 60.69% |
| Madison Horn | Democratic | 134,471 | 39.31% |
Bice won by 73,165 votes, a margin of approximately 21.38 percentage points. The figures come from the Oklahoma State Election Board’s November 5, 2024 results; the Washington Post/AP results page and NPR’s results presentation report the same outcome.
What the campaign raised and spent
The FEC candidate overview reports the following for the 2023–24 cycle through November 25, 2024:
Best Value
| Measure | Amount | Qualification |
|---|---|---|
| Total receipts | $591,403.83 | FEC report through November 25, 2024 |
| Total disbursements | $575,447.17 | FEC report through November 25, 2024 |
| Authorized committee | Oklahomans for Madison | Candidate ID H4OK05199 |
Those are cycle totals reported at that cutoff, not lifetime fundraising figures or proof that spending caused the election result. The source of record is the Federal Election Commission candidate page.
Is Madison Horn running for Congress in 2026?
The documented campaign and election are from 2024. As of August 18, 2026, the sources reviewed do not establish a new 2026 congressional campaign through an official filing, ballot record or direct campaign announcement. A 2026 Oklahoma voter guide lists Horn under District 5, but that listing alone should not be treated as confirmation of a candidacy. The Oklahoma election-results archive and the FEC record should be checked for authoritative updates.
What her campaign shows
Horn’s bid illustrates the opportunity and difficulty of turning specialized technical experience into an electoral identity. Cybersecurity gave her a concrete way to discuss national security, infrastructure, privacy and workforce preparation, while her Oklahoma and Cherokee Nation background supplied a local political narrative. The 2024 result also shows that professional credentials do not by themselves overcome party alignment, district conditions or the advantages of an incumbent.
