Future of an Aging Court Raises Stakes of Presidential Vote
The winner of the race for president will inherit a group of justices who frequently split 5 to 4 along ideological lines. That suggests that the next president could have a powerful impact if he gets to replace a justice of the opposing side.
This election could shape the court for decades to come, said Nan Aron, president of the Alliance for Justice, a liberal advocacy group.
It is, of course, impossible to predict when a vacancy will occur. (Justice John Paul Stevens spent 35 years on the court and retired at 90, while Justice Robert H. Jackson, who served in the 1940s and 1950s, died of a heart attack at 62.) A 2006 study in the Harvard Journal of Law and Public Policy found that the average retirement age for justices was 78.7.
Justice Ginsburg, a stalwart of the courts liberal bloc, has been treated for pancreatic cancer. Justice Antonin Scalia, the courts most visible conservative, is 76. Justice Anthony M. Kennedy, frequently the swing vote, is 75. And Justice Stephen G. Breyer, like Justice Ginsburg a Democratic appointee, is about to turn 74.
