Jan Crawford Greenburg reports that the White House has a short list of candidates to replace Justice Souter on the Supreme Court. According to Greenburg, the White House has asked six individuals to submit information for vetting, “which is being run outside the White House,” but only three — Diane Wood, Elena Kagan, and Sonia Sotomayor — are identified by name. Most interesting is Greenburg’s coverage of the internal debate over the nomination, over whether to seek political advantage or identify the nominee with greatest potential impact on the Court, whether to play it safe or whether to save a safer candidate for a subsequent nomination later in the term. Interesting stuff.
