On August 23, Bill Redpath, Libertarian Party nominee for U.S. House, Virginia’s 10th district, debated his Democratic Party opponent, Jeff Barnett.  See this story.  The third candidate in the race, incumbent Republican Frank Wolf, did not participate.  Thanks to Melinda Moore for the link.  Redpath is somewhat well known nationally because he was the chair of the Libertarian National Committee 2006-2010.
