The Supreme Court has issued a major ruling that could lead to the redrawing of many legislative districts for partisan reasons. The court largely upheld Texas’ controversial 2003 redistricting plan devised by former Congressman Tom Delay that helped Texas Republicans gain six seats in Congress. The Court said it was OK for state legislators to redraw district boundaries as often as they like. Up until now it was customary for states to redraw the districts once a decade based on new census information. The League of Women Voters, Common Cause and other groups criticized the court ruling because it is expected to lead to a new round of partisan gerrymandering. The Supreme Court didn’t fully back the Texas plan. It found that Texas lawmakers had violated the Voting Rights Act when it redrew the borders of one district to remove 100,000 Mexican-Americans in order to help a Republican candidate.
