(AP) — Buoyed by a recent U.S. Supreme Court decision, advocates of overhauling how Michigan draws legislative and congressional seats plan to raise public awareness about redistricting in preparation for a potential 2016 ballot initiative. Arizona voters had created an independent commission in 2000 to take the politically charged job out of the hands of the Legislature. The League of Women Voters and Common Cause, groups that advocate for fairer maps, are researching other states' redistricting systems and conducting polling before ramping up educational efforts with help from local civic groups. State Democratic Party Chairman Lon Johnson said the court decision "paves the way for Michigan to explore the option of a fairer system that better reflects voter sentiment in our state." Organizers of a constitutional amendment would have to collect about 315,000 valid voter signatures by next July to put the measure to a public vote in November 2016.
