JEFFREY ROSEN: “The Obama-Biden slate is historic in many ways, but for law professors it has a special cachet: It’s the first time that professors of constitutional law have occupied both slots on a ticket. . . . As chairman of the Senate Judiciary Committee, and the veteran of some of the most bruising Supreme Court confirmation battles, Biden did more than champion civil liberties. He developed an uncanny knack for making them politically palatable to Middle America. In fact, during the Robert Bork and Clarence Thomas hearings, he shepherded a new and expansive conception of privacy into public discourse. This gift for marketing civil liberties won’t just serve Obama well as he rebuts Republican attacks during the campaign; if the ticket prevails, Biden’s instincts will help guide the selection of judges and the challenging task of reconstructing civil liberties after the assault of the last eight years.”
