The required number of valid signatures for both statewide initiatives and referendums are the same. It is tied to the number of votes cast for the office of the Governor of Maine in the most recent gubernatorial election. Gubernatorial elections are held in Maine every four years. The requirement is 10% of the total votes cast for governor (excluding blanks) in the most recent election (2010) as established in Article 4, Part Third, Section 18, sub-section 2 of the Maine Constitution.
