Utahns have nine days to register or make any changes to their political party. The Utah County Clerk said the deadline to change party affiliation is Thursday, March 31.
Utah laws require registering with a political party in order to vote in the primary election which is on June 28. You can always choose to vote for a candidate from any party in general elections.
Changes to party affiliation can be made by mail, over the phone, or online atUtahCounty.gov.
