A three-judge panel hears arguments in federal court today over whether legislators relied too much on race when they drew legislative district lines. The fight over redistricting involves a divided U-S Supreme Court. Back in March the U-S Supreme Court sent the map back for and additional review. The Legislative Black Caucus says Republicans stacked and packed black voters into designated minority districts, limiting their ability to influence elections elsewhere. The district lines were drawn by the newly elected GOP majority. The state will have to hold new elections if the map is tossed. Lawmakers said they complied with the Voting Rights Act by preserving minority representation in the Alabama Legislature. They said voters were shifted to make legislative districts roughly the same size.
