Eric Barlow, a Wyoming state senator and Marine Corps veteran, is seeking the Republican nomination for governor in today’s primary election, August 18, 2026, as the frontrunner in a competitive race to replace term-limited incumbent Mark Gordon.
Barlow represents Campbell County in the Wyoming Senate and previously served five terms in the state House, including a stint as Speaker. A large-animal veterinarian and fourth-generation rancher from Gillette, he announced his candidacy in August 2025 and has positioned himself as a mainstream conservative focused on respectful leadership rooted in service rather than partisan politics.
The Republican primary features four candidates competing for the nomination: Barlow, Superintendent of Public Instruction Megan Degenfelder, retired Marine Corps Colonel Brent Bien, and Curt Blake. The winner will face Democrat Kenneth Casner in the November general election for the open seat.
Barlow has outraised his opponents in what amounts to Wyoming’s most expensive gubernatorial primary in recent history. According to campaign finance reports filed in mid-August, Barlow collected approximately $1.54 million in total contributions and carried-over funds since announcing his bid, beating Degenfelder by about $380,000. His campaign has raised roughly $3 million across all Republican candidates combined—far surpassing the $541,577 raised by Governor Mark Gordon in his 2022 primary and the $155,846 raised in 2018.
A distinctive feature of Barlow’s fundraising is his reliance on individual donors rather than loans or political action committees. Ninety-six percent of his campaign contributions came from individuals, according to WyoFile’s analysis of campaign filings. He received $148,306 in family contributions, including $30,000 each from his mother and his late father’s trust, plus $53,306 from himself. By contrast, Degenfelder’s campaign relied heavily on loans from her father—approximately $497,000, which represents roughly 40% of her total campaign funding.
The three leading candidates have pursued different fundraising strategies reflecting their campaign philosophies. Degenfelder received the most PAC funding at $392,500, with strong backing from Wyoming-based groups including Fight Wyoming Fight, which gave $290,000. Bien, who has emphasized grassroots support and refused money from some PACs, reported the lowest fundraising totals at $191,819 in contributions, though his campaign included significant anonymous and in-kind contributions representing nearly a third of his total support.
Barlow has emphasized energy development, public lands management, and economic growth in his messaging. He has received endorsements from sitting state senators and backing from political leaders including former House Speaker Tom Lubnau and former Wyoming Supreme Court Justice Bill Hill. His campaign has also drawn donations from notable figures in Wyoming politics and law, including attorney Ryan Semerad, who won a landmark public lands corner-crossing case.
The race comes as Wyoming Republicans select a successor to Governor Gordon, who has been described as moderate within the party. Prediction markets as of mid-August showed Barlow with an 81% to 84% probability of winning the nomination, with Degenfelder at roughly 15% to 21% and Bien trailing significantly. The primary results will determine which Republican candidate advances to face Casner in a state where Republicans hold strong electoral advantage.
