Elections for the Wyoming State Senate will take place in 2024. The general election is on November 5, 2024. The primary was Aug. 20, 2024. The filing deadline was May 31, 2024.

There were 11 contested Republican primaries for the Wyoming State Senate that took place on Aug. 20, 2024. Ballotpedia identified eight of those primaries as battlegrounds.

The primaries took place in the context of disagreements between two legislative caucuses. According to WyoFile, the state Republican Party was, at the time of the election, “divided between traditionalist and hard-line factions,” with the Wyoming Caucus representing the former and the Wyoming Freedom Caucus representing the latter. Since its founding, the Wyoming Freedom Caucus “managed to push through measures that initially appeared destined to die, such as legislation to restrict crossover voting and an abortion ban that’s now held up in court.”

Wyoming’s 2024 legislative primaries were more competitive than any in the preceding decade. There were the highest numbers of contested Republican primaries (54), Republican candidates running (141), and contested primaries involving Republican incumbents (41) than in any year since at least 2010.

The Prosperity and Commerce PAC, associated with Gov. Mark Gordon (R), and the Wyoming Hope PAC supported candidates aligned with the Wyoming Caucus. Former state legislator Allen Jaggi’s (R) Constitutional Issues PAC supported candidates aligned with the Wyoming Freedom Caucus.

The eight primaries Ballotpedia identified as battlegrounds included two elections where Wyoming Caucus-aligned and Wyoming Freedom Caucus-aligned candidates ran for open seats. The six battlegrounds with an incumbent on the ballot included four where the incumbent faced a Wyoming Caucus-aligned challenger and two where the incumbent faced a Wyoming Freedom Caucus-aligned challenger.

All six incumbents running in battleground districts won their primaries. The Wyoming Freedom Caucus-aligned candidate won both battleground primaries without an incumbent on the ballot.

As of Aug. 18, 2024, Republicans controlled the Wyoming Senate with a 29-2 majority. Fifteen seats were up for election. A Democratic candidate filed to run in three of those seats, meaning Republicans will maintain their Senate majority regardless of the election outcome.

As of the 2024 election, Wyoming was one of 23 Republican trifectas. A state government trifecta is a term used to describe a single-party government where one political party holds the governor’s office and a majority in both chambers of the state legislature.
