Well, Bob Barr has the nomination of the Libertarian Party as of yesterday. It sounds like the vote was close. Bob Barr, having strong conservative values, was not liked by a segment of the Libertarian base. The following video is the tail end of Christine Smith's comments where she spoke against Bob Barr. As you can hear, she was booed mercilessly for her comments. It turns out that Barr's support in the LP, and thus, support among conservatives in the LP is very strong.
