Revise donor privacy laws for certain political contributions

This bill updates Montana's political contribution reporting rules to protect the privacy of donors to 501(c)(4) organizations, commonly known as social welfare groups. It requires that the names and addresses of donors giving less than $1,000 to these organizations remain confidential and not be disclosed in public reports. The legislation directs the state political practices commissioner to create specific rules outlining how to handle these contributions and define small-dollar transactions. While most political contributions of $50 or more must still be publicly reported with donor details, this change creates a privacy exception for smaller gifts to tax-exempt social welfare groups.
