I'm still not sure about Barr.
The Libertarian philosophy can generally be described as being fiscally conservative and socially liberal. Barr has traditionally only been the first of those two. While he may have reversed his opinion on victimless drug use, I'd want to learn more about where he stands on some other issues before I'd throw my support behind him.
But, as always seems to be the case, he'll probably turn out to be a better choice than the other two candidates, both of whom are likely to take even more of our freedoms & money away.
