Only for a few years. Warner is going to run for president in 2012, and of course at that time he'll leave his Senate seat for the White House. Truth? I think he'll win.
Mark Warner would have a problem in 2012. If Hillary is President, he’ll have to challenge her, and that won’t happen. If Fred is the incumbent, he can run, but unless Fred has really made a mess of things, he won’t win, either. He’d be effectively shut out until 2016. Of course, if Hillary lasts until then (heaven help us), she’ll be backing Fat Boy Richardson to succeed her. Of course, we’ll be a 3rd world hellhole by then.
Warner’s going to likely have to face down Obama or (goodness forbid) O’Malley in the 2012 primaries.
