Utah election officials are sending letters to all independent voters, mentioning the upcoming primary (for office other than President). The letter asks if they wish a Democratic ballot, or a Republican ballot. The letter explains that if they want a Republican ballot, their registration record will be changed to list them as a Republican. The letter does not say this about the Democratic primary, because the Democratic Party lets independents vote in its primaries.

The Democratic Party has complained about the letter. See this story.

Utah has three other ballot-qualified parties: Libertarian, Constitution, and Independent American. Technically they also nominate by primary, but there are no primary contests for those three parties, because Utah only holds primaries when two competing candidates both show substantial support at a party caucus held before the primaries. The three smaller parties didn’t have any such contests this year.
