Millburn reached the 300-signature threshold and filed for the general election on June 16, the Davis County Clerk’s office confirmed Tuesday.

Millburn will face the winner of the Republican primary between two-term incumbent Lorene Kamalu and Susan Lee. There is no Democratic candidate.

Millburn served as Davis County commissioner from 2007 to 2018, eventually being replaced on the commission by Bob Stevenson, who is now challenging Trevor Lee for the House District 16 seat.

Millburn did not immediately return a request for comment.

Clarifying Millburn’s affiliation, Davis County Clerk Brian McKenzie said Millburn is not running under a party ticket.

“He may or may not be affiliated with a political party, but as a candidate, he’s running as an unaffiliated candidate,” he said.

Elaborating on the difference between an unaffiliated candidate and an independent candidate, McKenzie said independent in Utah usually refers to the Independent American Party.

“But generally, people say, ‘I’m independent,’ and they’re usually meaning that they’re not a member of a party,” he said. “And so he’s running on a nonparty ticket.”

In her reaction to the news, Kamalu emphasized the effect Millburn’s entry will have on voters as a positive.

“The really good thing about it is it keeps people engaged to keep learning,” Kamalu said. “A lot of people have learned a lot.”

Kamalu’s challenger in the Republican primary, Susan Lee, expressed confidence in the Republican nominee going forward.

“I still feel very strongly that the Republican on the ballot is going to end up winning,” she said, adding that she couldn’t remember it happening any other way.

She said she welcomed the challenge and said “it makes the process better.”
