The movement to take politics out of setting legislative district boundaries seemed to suffer a grievous, and perhaps even mortal, blow this spring when the Supreme Court passed up three chances to declare partisan gerrymandering unconstitutional.

But it turns out that reports of its death are exaggerated. As federal courts dither over how to resolve the issue, activists have begun tackling it state by state at the grass roots.

In Michigan, a proposed constitutional amendment to end gerrymandering, written and promoted by a nonpartisan group called Voters Not Politicians, will be on the ballot in November, unless blocked by a court challenge that has so far fallen short. So many Michiganders signed petitions to bring the measure to a vote — 110,000 more than state law requires — that the group ended its signature campaign 70 days short of the six months allowed.

In Missouri, another nonpartisan group called Clean Missouri needed 180,000 signatures to get its anti-gerrymander initiative on the ballot; it collected 346,000. Final certification is expected next month.
