Wyoming Redistricting Process


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


Legislative maps are enacted by the State Legislature. The Governor can veto the plans.

The Legislature can override a veto with a two-thirds vote. Republicans currently have veto-proof majorities in both chambers.

Governor Bill Signing

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 in initial 3 day period, the governor can sign or veto the bill within 15 days after adjournment; otherwise, it becomes law. Sundays are excluded in these calculations. Line-item vetoes are permitted.

Ballot Measure Process

Kinds of Ballot Measures
Indirect initiatives and referendums are permitted to amend statutes. Initiatives are not permitted to amend the state Constitution. Legislatively initiated ballot measures may amend the Constitution, but not statutes.

Single-Subject Rule
There is a single-subject rule.

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 is prohibited by the Constitution for enactment by the Legislature. Initiatives may not be filed if they are substantially the same as measures defeated within the last 5 years.

Signature Requirements
100 preliminary signatures of sponsors are required.

The signature requirement for statutory initiatives and veto referendums is 15% of all votes cast in the previous general election. Initiatives and referendums must also be signed by 15% of residents in at least two-thirds of the state’s counties, determined by total voters in the preceding general election in that county. 278,503 people voted in the 2020 General Election in Wyoming, so 41,776 signatures are required for statutory initiatives and veto referendums. County vote totals for the 2020 General Election can be found here.

Submission Deadlines
Initiative petitions do not have a constitutional submission deadline, but dates can be proscribed by law. Petitions will be voted upon 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 2022 general election ballot, petitions must be filed prior to the start of the legislative session in the year of the election (February 14, 2022). Referendums must be submitted within 90 days after the end of the legislative session and will be placed on the ballot of the first general election held more than 180 days after adjournment of the legislative session at which the act was passed.

Circulation Period
The circulation period for initiative petitions is 18 months.

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