Wyoming's At-Large U.S. House District Primary

Ten Republicans and two Democrats will compete in Wyoming's Aug. 18 U.S. House primaries for the right to succeed Rep. Harriet Hageman, who is leaving the House to run for U.S. Senate. The open-seat race has drawn a crowded Republican field and substantial candidate and outside spending ahead of the primary.

Wyoming sends a single at-large representative to the U.S. House, meaning the congressional district encompasses the entire state and all 23 counties, from Cheyenne and Casper to Jackson and the state's rural communities.

The Candidates

Republican Primary

Chuck Gray, Wyoming's current Secretary of State, is among the best-known challengers. A former three-term state legislator from Casper, Gray won the secretary of state's office in 2022 with a Trump endorsement, defeating a sitting state senator in the primary. He has campaigned on an "America First" platform focused on immigration enforcement, countering Chinese influence, protecting girls' sports, and defending Wyoming's energy industry.

Bo Biteman is the outgoing President of the Wyoming State Senate, a Sheridan County lawmaker from Ranchester who has served in the legislature since 2017. A self-described constitutional conservative, Biteman spent more than 20 years in the energy industry and 13 years as a volunteer firefighter before entering politics. He launched his congressional bid the day after the 2026 legislative session ended.

Jillian Balow served two terms as Wyoming Superintendent of Public Instruction from 2014 to 2022, then took on the same role in Virginia under Gov. Glenn Youngkin before resigning in 2023. With roughly 30 years of experience in K-12 education as a teacher, administrator, and elected official, Balow entered the race in January 2026 as one of its earliest candidates. Federal contribution records show she gave $125,000 to the race herself — the largest single individual contribution in the data.

Reid Rasner is a Casper-based businessman and wealth manager who announced his candidacy in January 2026, running under the slogan "Unapologetically, America First" with a focus on infrastructure investment and Wyoming energy. His campaign drew scrutiny in June 2026 after federal filings revealed he had been discharged from his broker clearinghouse over allegations of unapproved outside business activity.

Also running in the Republican primary are Frank Chapman, Kevin Christensen, David Giralt, Keith B. Goodenough, John Romero-Martinez, and Gavin Solomon.

Democrats

Lisa Kinney, a Laramie attorney, previously served in the Wyoming Senate from 1985 to 1995, including as Senate minority leader. Her career since leaving the Legislature has included work with the Albany County Public Library and the University of Wyoming. Elena Del Real also qualified for the Democratic primary.

The Money Behind the Race

Rasner has reported the most campaign receipts among candidates with current Federal Election Commission financial summaries. Reid Rasner for WY reported $2,043,826.65 in total receipts through June 30. However, only $328,761.99 of that amount consisted of contributions, including $319,689.47 from individuals and $9,072.52 in candidate contributions. The remainder includes substantial candidate financing.

Gray reported $1,378,842 in total receipts through June 30. Gray loaned his campaign $1,147,000, while his committee reported $228,436 in individual contributions and $2,500 from a party committee. The large candidate loan accounts for most of Gray's reported fundraising.

Balow reported $166,451.09 in receipts through June 30. Of that amount, $125,000 came from Balow herself, while $41,449.12 came from individual contributors.

Giralt has also raised six figures and entered July with $153,080.98 in cash on hand, according to the FEC. His committee reported $74,460.86 in debt through June 30.

Biteman's available FEC candidate summary reports $29,585.14 in receipts, all from individual contributors, although that summary covers activity only through March 31 and therefore does not provide a directly comparable picture of his campaign's current finances.

Outside groups have also spent heavily in the Republican primary. Protecting Wyoming Values, a super PAC registered with the FEC in April, reported $657,009 in receipts through June 30, all from individual contributions.

Ratings vs. Odds

The major election forecasters agree that Republicans are overwhelmingly favored to retain Wyoming's lone U.S. House seat despite Hageman leaving the House.

The Cook Political Report, Sabato's Crystal Ball and Inside Elections rate Wyoming's at-large district Solid Republican. The consensus reflects Wyoming's longstanding Republican advantage in federal elections and means the Aug. 18 Republican primary is likely to be considerably more competitive than the Nov. 3 general election.

Kalshi also gives the eventual Republican nominee an overwhelming advantage in the general election. The more immediate question is which Republican emerges from the crowded Aug. 18 primary. The winner will advance to November as the strong favorite to succeed Hageman as Wyoming's lone member of the U.S. House.
