Michigan voters will decide in November whether to entrust how their voting districts are drawn to an independent commission rather than the Legislature, which could alter the balance of power in a state that Republicans have controlled since 2010 and where Donald Trump eked out the slimmest of victories two years ago.
Three other states have redistricting initiatives on this year's ballots and there are ongoing legal challenges to the political boundaries in about a dozen states that claim they are the result of political or racial gerrymandering -- the process by which districts are drawn to favor the party in power.
The issue is particularly charged in Michigan, a battleground state in presidential elections that has some of the most Republican-skewed legislative districts in the nation, according to an Associated Press analysis.
