Dean Barkley is not a Libertarian, Ted Stevens lost because he committed felonies and the Democrats in DC engineered his verdict to come out days before the election.
In Georgia, there will not be a Libertarian in the runoff. It’s up to the Conservatives in Georgia to go out to vote for him to make sure Obama doesn’t have an 60 votes in Senate.
The point is there would not have been a runoff if the libertarian hadn’t been on the ballot.
