Republicans control both legislative chambers and hold all statewide offices.
The AP analyzed the 2016 election results using an "efficiency gap" formula developed by University of Chicago law professor Nick Stephanopoulos and researcher Eric McGhee of the nonpartisan Public Policy Institute of California.
Torr argues gerrymandering, whether to build and keep political power or, as some in the minority party argue, to build competitive races, is damaging.
