Chuck Gray leads the Wyoming at-large Republican primary field with strong trader consensus at 69% implied probability, driven by his current role as Secretary of State and established statewide name recognition in a crowded open-seat contest. The August 18 primary follows Harriet Hageman’s decision to run for Senate, creating an open House race where Gray has emphasized election integrity and energy issues through active campaigning, including recent parade appearances. Steve Friess trails at 26.5% amid a fragmented field that includes state Senate President Bo Biteman, former Superintendent Jillian Balow, businessman Reid Rasner, and several lower-polling challengers such as Kevin Christensen. The primary’s timing and Wyoming’s Republican voter base have reinforced Gray’s positioning as the front-runner ahead of tomorrow’s vote, though the multi-candidate structure leaves room for late shifts in support.
