I interviewed Libertarian presidential candidate Bob Barr this afternoon (video to come). He made some interesting points, including saying that McCain's nomination as the GOP candidate made his decision to run easy. His answer to the "spoiler" question was similar to Nader's -- essentially, that if McCain can't win enough votes, he doesn't deserve to be president. We also had a very interesting debate regarding civil rights versus security.
He also told me he was talking with Ron Paul and his staffers, and hoped to replicate some of his success in exciting young people, and in using the internet.
