HOFELLER'S MAPS USED COLOR CODE TO GUIDE GOP GERRYMANDERING: Christopher Cooper, a professor at Western Carolina University and expert witness for the challengers in the gerrymandering case, took the judges, lawyers and members of the public in court Friday through the Hofeller files. Cooper pointed specifically to two factors in the files that he said showed Hofeller worked hard to make sure the legislative districts would give Republicans an unfair partisan edge. Hofeller color-coded the state’s political leanings, Cooper said, using a traffic light system of green for Republican areas, yellow for tossup areas, and red for Democratic areas. His color-coding went down to the neighborhood level, broken up into individual voting precincts. “It shows that partisanship was front and center,” Cooper said.
