Will is inclined to this sort of snobbery. I didn't even approve of the way he took after Jimmy Carter. The Olympian tone, I mean.
Among the current justices, 5 received their LLBs from Harvard (Roberts, Scalia, Kennedy, Souter, and Breyer), one from Yale (Thomas), and one from Columbia (Bader-Ginsberg who also attended Harvard Law). O'Connor (Stanford) and Stevens (Northwestern) were the exceptions.
