Penn Jillette had this to say afterward:
Bob Barr said, ‘Republicans have become the party of fear. Democrats are the hate. And there’s lots of room for the rest of us.’ And I think that should somehow be the Libertarian slogan. I don’t want to be scared of everything and I don’t want to think that everybody is hateful and out to get us. You know, I think we should live with as much freedom as possible and trust people as much as we can. I like Bob Barr and I like Wayne Root and I’ll probably…I was really proud to have them back stage and they were fun to talk to.
