On May 17, Idaho held primaries for the four ballot-qualified parties, Republican, Democratic, Libertarian, and Constitution. This was the first time Idaho had held a Libertarian primary since 2002. When there are no contests in a party’s primary, the state doesn’t print up primary ballots for that party, and everyone who filed for the primary is deemed nominated.
Here is a link to the Secretary of State’s website, showing unofficial 2022 primary results. Somewhat more than 700 voters used a Libertarian primary ballot. Back in 2002, there were 1,179 voters who chose a Libertarian primary ballot, but back then, Idaho didn’t have registration by party and any voter was free to choose any party’s primary ballot.
Somewhat more than 516 voters in 2022 used a Constitution primary ballot.
