Incumbent Ogden Driskill faces a strong challenge from House Speaker Chip Neiman in the August 18 Republican primary for Wyoming State Senate District 1, a contest that underscores divisions between GOP factions. Neiman, aligned with the Freedom Caucus, resigned his speakership to run and holds higher lifetime ratings from conservative groups on issues such as taxes, spending, and platform adherence, while Driskill, a former Senate president serving since 2010, draws support from more traditional party elements. With the vote days away across Campbell, Crook, and Weston counties, trader consensus shows Neiman as the narrow frontrunner at 54.5% implied probability versus Driskill's 23%, reflecting the race's competitiveness and limited polling or late endorsements that could still shift outcomes.
