002-18 Wyo. Code R. § 18-5
(a) These rules apply to all candidates whose name appears on the ballot of an election administered by a County Clerk and are to be used when a candidate withdraws from an election.
(b) Upon receipt of written and signed notification by a candidate of his intention to withdraw from a race, a candidate's name will be removed from the ballot. If the ballot has been finalized and approved for printing prior to notification, the County Clerk will prominently post a notice at each polling place declaring the withdrawal. The notice shall state the full name of the candidate as it is printed on the ballot, the office the candidate was seeking, and all other pertinent information the County Clerk deems helpful to the voters. If the withdrawal notice is received by a filing office other than the County Clerk, a copy of the withdrawal will be immediately transferred to the County Clerk conducting the election.
(c) Prior to election day, but during absentee voting, the notice shall be posted in a prominent location at all absentee voting locations so it is easily visible to all absentee voters. A withdrawal notice shall be included with all absentee ballots mailed to voters effective from the day of formal notice of withdrawal to the end of the absentee balloting process.
(d) If time allows, notice should be provided with the publication of the sample ballots and polling place information.
(e) Once a candidate has withdrawn his name from the election, he may not subsequently change his mind and request his name be placed on the ballot. If the time for filing nomination applications has not yet closed, a candidate who has withdrawn may file another application.
