A Court with no Protestants . . . for real

Elena Kagan, the Solicitor General, will be nominated by President Obama to replace retiring Justice John Paul Stevens.  And, she will almost certainly be confirmed, which means that, in a few months, the Supreme Court of the United States will have no Protestant members.  I have some ideas about how this happened . . . but I'm still not sure what (if anything) it means, going forward.  We'll see!
