Generally revise surplus campaign funds laws

This bill amends Montana's campaign finance laws to allow legislative candidates to donate up to $10,000 of leftover campaign funds to their own future campaigns. Under the new rules, candidates must still dispose of any remaining surplus within 120 days after filing their closing report, but they now have an exception for this specific contribution limit. The law clarifies that these funds count as a personal contribution rather than a loan and must be reported separately on the closing campaign report. Statewide elected officials and public service commissioners can also establish continuing service accounts for future use. The changes apply only to legislative candidates and do not affect other types of candidates or campaign fund usage.
