Republican Eric Barlow faces Democrat Kenneth Casner and Constitution Party candidate Rebecca Bextel in the November 3 general election for an open seat in solidly Republican Wyoming. Barlow secured the GOP nomination in the August primary with roughly 45 percent of the vote against stronger challengers than in prior cycles. No general-election polls have emerged since the primary, leaving trader assessments anchored in the state's consistent partisan lean, where Republicans have won every statewide contest since 2006 and Donald Trump carried the state by more than 45 points in 2024. The third-party presence and limited Democratic infrastructure keep the expected margin in the 30-to-45-point range reflected in current pricing, with separation likely to widen only if late campaign spending or turnout data shifts baseline expectations before election day.
