The bill proposes an amendment to Article IV, section 2 of the Montana Constitution, specifying that only a citizen of the United States who is 18 years of age or older and meets the registration and residence requirements is considered a qualified elector. The amendment removes the word "Any" and replaces it with "Only a," thereby clarifying the eligibility criteria for qualified electors. Additionally, it maintains the existing exclusions for individuals serving a felony sentence or deemed of unsound mind by a court.

The bill also includes provisions that outline the legislative process for amending the constitution, requiring a two-thirds affirmative roll call vote from all members of the legislature for passage. It establishes that the act will take effect upon approval by the electorate and mandates that it be submitted to the qualified electors of Montana during the general election in November 2026, with specific language to be printed on the ballot for voter consideration.
