Courts take another look at the cold science of gerrymandering

Gerrymandering was once a kind of artisanal branch of politics. The late U.S. Rep. Phil Burton was said to have single-handedly redrawn the 1970 congressional map of California armed with nothing more than a stack of telephone books and his encyclopedic knowledge of the political landscape of his state. But computerization has turned it into a cold science. This year, the U.S. Supreme Court will try again to decide when gerrymandering goes too far.
