Enact laws to close primary elections In Montana.

This bill (LC 3237) proposed changing Montana's primary election system to require voters to be registered with a political party to participate in that party's primary election. It would have directly affected Montana voters who are unaffiliated or registered with a different party than the primary they wished to vote in. The bill aimed to establish closed primaries as the standard process for selecting candidates. However, the draft was placed on hold in March 2025 and ultimately died in the legislative process on May 27, 2025, meaning it never became law.
