Utah elects its statewide state constitutional officers in presidential years. For Treasurer and Auditor, no Democrat ran. This made it possible for the Libertarian, Constitution, and United Utah Parties to poll over 10% of the vote in at least one of those races. The minor party vote for each of those offices was approximately 25%. See the results here. The Utah vote test is 2% for any statewide race at either of the last two elections.
The Independent American Party went off the ballot, because it didn’t poll as much as 2% for any statewide race in either 2018 or 2020.
