The session of the U.S. Supreme Court that just ended wrapped up its latest round of rulings by making some important rulings on telecommunications, campaign finance reform, birth control and other hugely significant topics. Two-thirds of the Court’s rulings were unanimous, the first time that’s happened since the 1950s. What’s going on, and why? On this weekend’s new edition, Bill Moyers interviews two veteran Supreme Court watchers: Linda Greenhouse of The New York Times and Daliah Lithwick, a senior editor and columnist at Slate.
