WASHINGTON (Reuters) - In a major blow to election reformers, the U.S. Supreme Court on Thursday rejected efforts to rein in electoral map manipulation by politicians aimed at entrenching one party in power, a practice known as partisan gerrymandering that critics have said warps democracy.
The justices, in a landmark 5-4 ruling that could reverberate through U.S. politics for years to come, ruled for the first time that federal judges do not have the authority to curb partisan gerrymandering - a decision that could embolden state lawmakers to intensify use of the practice.
