An article in Scientific American examines how mathematical and geometric analysis can reveal when voting districts have been drawn to favor one political party.
A federal judge blocked use of Missouri's old congressional districts while the U.S. Supreme Court denied a request to use a new Republican-favored map, creating uncertainty less than two months before November's elections.
The court declined to intervene in Missouri's redistricting dispute, allowing the state supreme court ruling requiring voter approval of new districts to stand.
The court left in place a state ruling that blocked new district lines from taking effect before the November midterms, dealing a setback to Republicans’ national redistricting push.
