Voters are headed to the polls today to decide on three proposals. One of the proposals is a possible constitutional amendment which would establish a commission of citizens with exclusive authority to adopt district boundaries for the Michigan Senate, Michigan House of Representatives and U.S. Congress, every ten years. The commission would be randomly selected by the Secretary of State. The proposal would prohibit partisan officeholders and candidates, their employees, certain relatives and lobbyists from serving as commissioners. It would establish new redistricting criteria and would not allow for disproportionate advantage to political parties or candidates. Polls are open until 8 p.m. this evening.
