HARRISBURG, Pa. (AP) -- Registered Democratic voters suing to overturn Pennsylvania's Republican-crafted map of congressional districts want the state Supreme Court to redraw the district borders if the Legislature and governor can't do it within two weeks.
The plaintiffs outlined their arguments in a 76-page brief filed Friday with the state Supreme Court.

The plaintiffs' brief calls the map of 18 congressional districts "impervious to the will of voters." They want it to be redrawn using nonpartisan criteria. The map's been used in three elections.
A state judge told the Supreme Court last month that the challengers didn't prove the map violates existing law by unfairly favoring Republicans.
