Recent Voting Changes in Montana
New state legislative maps take effect in 2024 that may change the boundaries of your districts and affect which candidates appear on your ballot.
A federal judge has temporarily blocked a 2023 law that requires voters who were registered in another county or state to show their prior registration information when registering. The law also made it a crime to register in Montana while “purposefully” registered in another state. Litigation is ongoing.
The state Supreme Court upheld a lower court decision striking down laws that eliminated same-day registration, introduced new voter ID requirements, and prohibited paid efforts to collect absentee ballots.
