North Carolina: Redistricting skews North Carolina maps for Congress, General Assembly | News & Observer
North Carolina’s congressional and state House districts are among the most Republican-skewed in the country despite voter preferences that are relatively evenly split, according to an Associated Press analysis. The AP calculated the partisan advantage for North Carolina Republicans in the 2016 state and federal House races through a new statistical tool that’s designed to detect cases in which a political party maintained or increased its grip on power through how it drew voting districts. The measurement, known as the “efficiency gap,” has separately gained attention as a key argument in a pending Supreme Court case from Wisconsin that alleges partisan gerrymandering. It’s also cited by groups challenging the design of North Carolina’s congressional map, though the Republican defendants argue the measure shouldn’t be used as a legal standard. In the nationwide AP analysis, North Carolina had the highest efficiency gap – or greatest Republican advantage – among the roughly two-dozen largest states that determine the vast majority of Congress.
