Wyoming Election Odds — 2026 Live Betting Odds & Voting History

Three open seats in the most Republican state in the country. Sen. Cynthia Lummis announced December 19, 2025 that she would not seek a second term, citing energy demands of the office at age 71. U.S. Rep. Harriet Hageman — the at-large House member who unseated Liz Cheney in the 2022 Republican primary with Trump’s endorsement — declared for Senate four days later and received Trump’s immediate endorsement. That cleared her House seat too. Governor Mark Gordon is term-limited. The result is the rare Wyoming cycle where every federal office on the ballot is open — a single sweep of statewide turnover unprecedented in the state’s modern history. Trump won Wyoming by 46 points in 2024, the largest state-level margin nationally. All three seats will stay Republican. The races are all about which Republicans win them.

Wyoming governor betting odds

Wyoming’s two-term constitutional limit means Mark Gordon’s tenure ends in January 2027. Gordon, the former state treasurer (2012-2019), won the 2018 and 2022 gubernatorial races and is now term-limited.

Republican primary (August 18, 2026) — the de facto general election. Sprawling field:

• State Sen. Eric Barlow (R-Gillette), announced August 2025, focused on public lands and energy
• State Senate President Bo Biteman — declared after the 2026 legislative session, championed the Wyoming Energy Dominance fund
• Secretary of State Chuck Gray — running for governor after Hageman declined the gubernatorial race
• Superintendent of Public Instruction Megan Degenfelder — Trump-endorsed early in 2026, has built a broad institutional endorsement list including former state House and Senate leadership
• State Treasurer Curt Meier
• Cody businessman Brent Bien, Cheyenne resident Joseph Kibler, Reid Rasner, others

Democratic primary: Limited field. No Democrat has won statewide office in Wyoming since 2002.

Hageman’s December 2023 decision to skip the gubernatorial race (despite leading early polling) reshaped the GOP primary. Degenfelder is currently the Trump-aligned frontrunner; Biteman is the legislative-leadership candidate; Gray is the secretary-of-state-running-up option.

Cook rates Solid Republican. The general election is decided in the August primary.

Wyoming presidential election betting odds

No state went redder for Trump than Wyoming in 2024 — a 46-point margin, the largest in the country, exceeding West Virginia (42 points) and Oklahoma (33 points). Wyoming has voted Republican in every presidential election since 1968, and has not voted Democratic for president since Lyndon Johnson’s 1964 win.

Cook PVI rates Wyoming R+25 — the most Republican PVI in the country. The 3 electoral votes are safe Republican for 2028.

The state’s most prominent political export of the last decade was former U.S. Rep. Liz Cheney, who broke with Trump after January 6 and lost the 2022 Republican primary to Hageman. Cheney has no current Wyoming political base.

Wyoming senate betting odds

Cynthia Lummis announced her retirement December 19, 2025, citing energy demands at age 71. She has a 46-year career in Wyoming public service (state legislature, state treasurer, U.S. House from 2009-2017, and U.S. Senate since 2021). She is the most prominent crypto policy advocate in the Senate. Her retirement was a surprise — Trump had endorsed her re-election in March 2025.

Republican primary (August 18, 2026):

• U.S. Rep. Harriet Hageman, who declared December 23, 2025 — four days after Lummis’s announcement. Trump endorsed her immediately (“TOTAL WINNER”). Hageman previously beat Liz Cheney in the 2022 House primary by 38 points with Trump’s backing. She has the endorsement of fellow Republican Sen. John Barrasso, the outgoing Sen. Lummis, and most of the state party establishment.
• Jimmy Skovgard, Wyoming Army National Guard veteran, is the only other Republican on the ballot.

Democratic primary: Limited candidates with no realistic path to the general election.

Hageman is essentially the next senator. Cook rates Solid Republican. Wyoming has not elected a Democrat to the U.S. Senate since 1970.

Wyoming house betting odds

Hageman’s Senate run leaves Wyoming’s at-large House seat open. The seat is open because Hageman is running for Senate.

Republican primary: Crowded field has formed, including Casper businessman Reid Rasner (actively campaigning since early 2026), former Wyoming Superintendent of Public Instruction Jillian Balow, and Casper-based military veterans David Giralt and Kevin Christensen. Secretary of State Chuck Gray briefly considered the House race before opting for governor.

Democratic primary: Minimal candidates. Wyoming Democrats have not won the state’s at-large House seat since 1976 (Teno Roncalio).

The general election will be Solid Republican regardless of primary outcome. No mid-decade redistricting (Wyoming has only one at-large seat). Primary August 18, 2026.
