The constitutionally dubious practice of states using race as a variable to redraw congressional districts, which largely shifts power to Democrats in the House of Representatives, is being called into question before the Supreme Court in a Louisiana case that could set a strong precedent for the rest of the country.After hearing 80 minutes of arguments in March, the Supreme Court is scheduled to hear additional arguments Oct. 15 to arrive at a decision in Callais v. Louisiana and determine whether a state using race as a variable in redistricting violates the 14th and 15th amendments to the Constitution. The ruling will set a precedent on the controversial practice of race-based redistricting and have a significant impact on the rest of the country’s redistricting process ahead of the battle for control of the House of Representatives next year.
