Boucher has been in office since 1982, when he defeated long-term incumbent Republican Bill Wampler. Boucher is regularly re-elected with around 60%. His previous opponents have been:
1982-Rep. Bill Wampler
Kilgore wouldn't get a free pass in a primary. Both 2004 candidate Kevin Triplett and Delegate Bill Carrico are likely candidates. A convention battle that pits social conservatives (Kilgore) against fiscal conservatives (Triplett) and then throw in law-and-order conservatives (Carrico) is just asking for trouble. There would be no way to beat Boucher even if the 9th district GOP rallied around one candidate (case in point, 2004 and 2002).
I would love to see a Boucher/Kilgore race. Boucher needs to have a little fun every two years. And somebody like Jerry Kilgore would be killed in a debate, if both could agree to one.
