The Supreme Court’s year usually follows a predictable pattern. The term, as the Justices call it, begins on the first Monday in October, and through the fall they usually hear a series of low-profile cases. The more controversial cases tend to come up in the first days of the new year, and the crescendo arrives in June, when the most important decisions are announced. This year, though, the drama came early, as the Court was given a chance to intervene and stop some onerous voting restrictions, passed by Republicans after their landslide victories in 2010, from going into effect. Given a historic opportunity, what did the Court do? Not much.
