Wyoming Redistricting Process


As of the 2020 Census, Wyoming has only one at-large congressional district.


Primary Authority: Legislative plans are enacted by the Wyoming State Legislature, subject to the Governor’s veto. The Legislature can override a veto with a 2/3 vote in each chamber. Republicans currently have veto-proof majorities in both chambers.

If a bill is presented to the governor during session, the governor has 3 days to sign or veto it; otherwise, it becomes law without signature. If the legislature adjourns during this initial 3-day period, the governor can sign or veto the bill within 15 days after adjournment; otherwise, it becomes law. Sundays are excluded from these calculations.

Mapping Timeline: Legislative plans must be enacted by the end of the first budget session of the Legislature following the decennial census. [Wyo. Const. art. III, § 48]

Redistricting Criteria: None.

Map Challenges: Not specified.

Ballot Measure & Referendum Processes

Types of Measures: Initiatives are permitted to amend statutes but not the state constitution. Referendums on statutes are permitted. Legislatively initiated ballot measures can amend the state constitution but not statutes.

Single-Subject Rule: Yes.

Initiative Subject Restrictions: Initiatives are not permitted to dedicate revenues; make or repeal appropriations; create courts; define the jurisdiction of courts or prescribe their rules; enact local or special legislation; or enact anything that the Legislature is prohibited from enacting by the state constitution. Initiatives cannot be filed if they are substantially the same as measures defeated within the last 5 years.

Signature Requirements: 1000 preliminary signatures of sponsors are required. Statutory initiatives and veto referendums require signatures equal to 15% of all votes cast in the previous general election in Wyoming in addition to 15% of residents in each of at least 2/3 of the state’s counties, as determined by total voters in that county in the previous general election. 198,198 people voted in the 2022 general election in Wyoming, so 29,730 signatures are required for statutory initiatives and referendums. County vote totals for the 2022 general election can be found here.

Submission Deadlines: Initiative petitions do not have a constitutional submission deadline, but deadlines can be prescribed by law. Successful petitions are to be voted on in the first statewide general election held more than 120 days after the adjournment of the legislative session. Therefore, for initiatives to be placed on the 2024 general election ballot, petitions must be filed prior to the start of the legislative session in the year of the election. Referendums must be submitted within 90 days after the end of the legislative session in which the law was passed. They are placed on the ballot of the first general election held more than 180 days after adjournment of the legislative session in which the law was passed.

Circulation Period: 18 months for initiative petitions.

Ballot Title and Summary: The summary is written by the Secretary of State with assistance from the Attorney General. Expedited reviews for summary are permitted.

Other Requirements: A fiscal impact statement is required only if the Secretary of State determines that the proposition will impact the state’s economy. Circulators are required to be a citizen of the United States and at least 18 years old. Any ballot measures require approval from a majority off the ballots cast in the election. The Legislature cannot repeal a measure passed by voters until two years have passed since it was made into law, but the Legislature can amend that measure through a majority vote. Referendums cannot target dedications of revenue; appropriations; local or special legislation; or laws necessary for immediate preservation of the public peace, health, or safety. Initiatives are permitted on general election ballots, but not on primary, special, or odd-year election ballots.
