In an unfortunate move, the Supreme Court upholds gerrymandering in Pennsylvania: The court affirmed on a 5-4 vote boundaries drawn by the Republican-controlled Pennsylvania Legislature, rejecting a challenge from state Democrats. Four court conservatives would have gone even further, by blocking legal attacks on gerrymandering, the practice of drawing voting districts to favor a political party. Those justices -- Chief Justice William H. Rehnquist, Sandra Day O'Connor, Antonin Scalia and Clarence Thomas -- wanted to overrule part of a 1986 high court ruling that permitted challenges. A fifth moderate conservative, Justice Anthony M. Kennedy, disagreed, as did four liberal justices. Kennedy voted with the conservatives in upholding Pennsylvania's new map. This is good news for incumbents and Republicans and bad news for the rest of us.
