Incumbent Ogden Driskill faces a strong challenge from House Speaker Chip Neiman in the August 18 Republican primary for Wyoming State Senate District 1, covering parts of Crook, Campbell, and Weston counties. Traders price Neiman at 79% amid his decision to relinquish the speakership and enter the race, reflecting Freedom Caucus influence and intra-party tensions over legislative priorities that surfaced in recent months. Driskill, who has held the seat since 2011 and previously served as Senate president, sits at 19% as the contest highlights divisions between establishment and more activist Republican factions. The primary's proximity amplifies focus on candidate positioning, endorsements, and turnout among core Republican voters, with limited polling available to benchmark the implied probabilities.
