Virginia Senator John Warner (former husband of Elizabeth Taylor. Also long-time head of Senate Armed Services committee) is not seeking another term. This clears the way for Mark Warner (Virginia's super popular Democratic ex governor; also former Nextel executive). If Mark Warner does run for the Senate (instead of holding out for VP), he looks pretty likely to win. Unless the GOP finds another Warner to run against him, just to totally confuse voters.
Hey, it's happened before.
