Chip Neiman, the current Wyoming House speaker challenging longtime incumbent Ogden Driskill in the August 18 Republican primary for Senate District 1, leads as the trader consensus favorite at 72 percent implied probability. The matchup highlights divisions within the state GOP between Neiman’s Freedom Caucus-aligned faction and Driskill’s more establishment record, including differences over legislative priorities and party platform adherence. A candidate debate earlier this month and recent coverage of the contest underscore the race’s visibility, while Driskill’s 24 percent reflects his incumbency advantage in the northeastern district covering Crook, Campbell, and Weston counties. No other candidates register meaningful support, leaving the outcome dependent on primary turnout among Republican voters.
