Partisan control in 2025
- See also: State government trifectas
Wyoming was one of 23 Republican state government trifectas at the start of 2025 legislative sessions. A state government trifecta occurs when one political party holds the governor's office, a majority in the state Senate, and a majority in the state House. For more information about state government trifectas, click here.
Wyoming was also one of 20 state legislatures where Republicans had a veto-proof supermajority in both chambers. Veto overrides occur when a legislature votes to reverse a veto issued by an executive such as a governor or the president. If one party has a majority in a state legislature that is large enough to override a gubernatorial veto without any votes from members of the minority party, it is called a veto-proof majority or, sometimes, a supermajority.

Legislatively referred constitutional amendments
In every state but Delaware, voter approval is required to enact a constitutional amendment. In each state, the legislature has a process for referring constitutional amendments before voters. In 18 states, initiated constitutional amendments can be put on the ballot through a signature petition drive. There are also many other types of statewide measures.
The methods by which the Wyoming Constitution can be amended:
The Wyoming Constitution provides two mechanisms for amending the state's constitution—a legislative process and a state constitutional convention. Wyoming requires a simple majority vote (50% plus 1) for voters to approve constitutional amendments.
Legislature
A two-thirds vote is required during one legislative session for the Wyoming State Legislature to place a constitutional amendment on the ballot. That amounts to a minimum of 42 votes in the Wyoming House of Representatives and 21 votes in the Wyoming State Senate, assuming no vacancies. Amendments do not require the governor's signature to be referred to the ballot.
Convention
According to Section 3 of Article 20 of the Wyoming Constitution, a two-thirds (66.67%) vote is required during one legislative session for the Wyoming State Legislature to place a constitutional convention question on the ballot. If a simple majority of voters approve the question, then the legislature needs to call for a convention during its next session.
