A panel of three federal judges delivered a welcome but frustrating ruling Thursday. The judges unanimously found that 28 of North Carolina’s 170 legislative districts were illegally drawn to concentrate black voters in a way that minimized their statewide political influence. U.S. Circuit Judge James Wynn wrote in the panel’s ruling that “… plaintiffs, and thousands of other North Carolina citizens, have suffered severe constitutional harms” from districts that were improperly drawn to bolster Republican control of the General Assembly. But the court also said the Nov. 8 election is too close to change the maps and that changes would have to be made afterward.
