I've been trying to find a spot for him too. I don't think he's finished. At least not in Virginia.
But I wouldn't relish a primary fight between Allen, Bolling and McDonnell. They'd have to cut a deal behind the scenes...or just not bother running and give it to the RATS.
Webb being a Veteran helped him cut into the GOP advantage in Norfolk and Va Beach. Also Webb's "Born Fighting" gimmick helped him in Southwest Va. These factors caused Allen to run behind Bush's numbers. To oust Webb six years from now, we need a veteran to hightlight Webb's expected liberal voting record.
Also it there any word about John Warner retiring? If Mark Warner goes for that Senate seat, it is an easy RAT gain. OTOH, if Mark Warner decides to be Hillary's Veep instead, then the Senate seat is a easy hold for Tom Davis.
