The Federalist Society just released a 2½-minute video I wrote and narrated on this subject. (The video is part of a new Federalist Society project, and will likely be the first of many.) Many thanks to Ozymandias Media for its design work, and to Lee Otis, Tyler Lowe, and my coblogger Nick Rosenkranz for all their help. If you like it, please pass it along to others who you think might be interested.
