Continuing a tradition of 20+-years’ standing, The Virginia Bar Association will again this year host a debate between candidates for major statewide political office. The debate will be held on Saturday, July 22 at 10:30 A.M. at The Homestead in connection with the VBA’s annual Summer Meeting to be held on July 20-23 and will feature incumbent Republican U.S. Senator George Allen and the winner of the June 13 Democratic primary, either Harris Miller or Jim Webb, who will be seeking to unseat Allen.
