Harvardites and Yalies, pointing to grads like Sotomayor, argue that their schools have long been meritocracies. True enough. Still, powerful alumni like Obama tend to brandish them the way English lords flaunt the Oxford-Cambridge Old Boy network. "It's a perfectly incestuous academic cartel," says Jonathan Turley, a legal scholar and professor at the George Washington University School of Law (another top 25 school) who teaches a course on the Supreme Court. Turley notes that after Kagan's White House presentation, most of the breathless buzz from cable TV pundits was "how plugged in she is to that exclusive Harvard-Yale club, that she knows the other justices because of their law school associations. It's a self-replicating system."
