On March 24, attorneys for the state of Wisconsin asked the U.S. Supreme Court to reverse a 3-judge U.S. District Court that, last year, had ruled that Wisconsin legislative districts consist of an unconstitutional partisan gerrymander. The case is Gill v Whitford, 16-1161. Here is the brief of the state. Thanks to Rick Hasen for this news. The voters who brought the case, and who won it in the court below, are Democrats.
