Generally revise voting laws related to individuals of unsound mind

This bill updates Montana's voting laws to clarify definitions related to individuals with mental health conditions and expands the definition of disability to include those whose mental or physical impairments make voting difficult. It revises existing statutes to provide clearer definitions for terms like "unsound mind," "penal institution," and "mental health facility," which directly affects how election officials determine voter eligibility and registration requirements. The legislation amends multiple sections of the Montana Code Annotated to ensure consistent terminology across voting procedures and to better protect the voting rights of people with disabilities while maintaining existing election administration standards.
