(CONSTITUTIONAL) Shall there be an amendment to the Colorado constitution making it more difficult to amend the Colorado constitution by requiring that any petition for a citizen-initiated constitutional amendment be signed by at least two percent of the registered electors who reside in each state senate district for the amendment to be placed on the ballot and increasing the percentage of votes needed to pass any proposed constitutional amendment from a majority to at least fifty-five percent of the votes cast, unless the proposed constitutional amendment only repeals, in whole or in part, any provision of the constitution?
