If you're not familiar with SCOTUSblog and its sister, the Supreme Court Nomination Blog, please visit them. The latter is buzzing this morning that "our best information is that the President will appoint [Fifth Circuit Judge] Edith Clement within the next forty-eight hours." UPDATE: The Associated Press reported within the past 15 minutes that the nomination might happen as early as this afternoon (via How Appealing). UPDATE: CNN is now reporting that D.C. Circuit Judge John Roberts, Jr. will be the nominee. The Supreme Court Nomination Blog has a similar report.
