The ruling came after U.S. congressional candidate Jimmy Skovgard filed a lawsuit against the state’s closed primary election system . Skovgard, along with six voters, brought the suit claiming that the party affiliation deadline interferes with some voters’ ability to choose him in the primary election. Skovgard claimed that Wyoming’s party affiliation deadline interferes with his ability to “associate with willing supporters who want to vote for me in the Republican primary. Skovgard’s lawsuit would have paused Wyoming’s closed primary rules. Only registered party members are allowed to vote in a closed primary election , and will see only that party’s candidate on the ballot.
