This article establishes a two phase pilot project that will allow certain municipalities to vote by mail. Phase one authorizes Class IV municipalities to conduct only early voting for municipal elections by mail beginning with the municipal election of 2010. Phase two authorizes five municipalities in the state to conduct all voting by mail beginning with the primary election of 2011. The pilot project will permit registered and other qualified voters of the authorized municipalities to vote a ballot by mail during the pilot program period. The Class IV municipalities that choose to participate in phase one may conduct only the early voting for the municipal elections entirely by mail. The five municipalities selected for participation in phase two may conduct both the primary and general elections entirely by mail.
