Mississippi's Gov. Haley Barbour, a Republican, will appoint Lott's replacement, who will serve until the 2008 elections, when voters will elect someone to serve out the balance of Lott's term, which runs through 2012. Rep. Chip Pickering of Mississippi, a former Lott aide who recently announced his retirement from the House, is widely seen as a potential successor. Pickering could not immediately be reached for comment.
