I know people have trouble looking at the issue of religious diversity on the Supreme Court. I raised this question when Justice Souter stepped down, and Obama's nomination put a 6th Catholic on the Court.
Here I am on a May, 4, 2009 Bloggingheads with Emily Bazelon, raising the question question of religious diveristy in the wake of the Souter retirement. (This recorded on May, 4, 2009 , before Obama had nominated Sotormayor.)
Now, Justice Stevens is the only Justice who was raised in the Protestant tradition. The other 2 Justices are Jewish. I anticipate that there will be little discussion of this, but I find it hard to believe that Obama will not see the lack of diversity as a problem and choose a Protestant.
