Various outlets are reporting that Elena Kagan is the next Supreme Court nominee. Although the sources are reputable, I will not be sure until Kagan is at the podium with President Obama. Various outlets also reported that Edith Brown Clement was going to replace Justice O'Connor and we all remember that John Roberts showed up at the podium--with Jack in his seersucker suit, on the move. My favorite get from the 2006 Jan Crawford interview with Chief Justice Roberts was that Jack was not dancing, he was being Spiderman "shooting the webs off."
Update (10:21 AM): Webs shot. Congratulations Solicitor General Kagan.
