Diversity throughout the history of The Court

I'm sure many of you have seen this Jeffrey Toobin piece on the history of seeking diversity on the Supreme Court. By chance you haven't definitely give it a read. The points he makes are pretty obvious ones for anyone who's interested in not just the history of SCOTUS but who's read anything at all on 19th Century American political history. Toobin though is the first major commenter I've seen who's actually voiced these obvious parallels. They're important points and I hope this piece is read widely.
