rtbohan compares Bob Barr with William Wirt:
This year, there is a feeling among some that, in Bob Barr, the Libertarian Party has nominated its own version of William Wirt. It has chosen a candidate whose political career as an office holder has been as a conservative, with a preference for smaller, cheaper government but little else of a libertarian about him. His most notable actions, and those on which he spent the most effort, attacking medical marijuana, supporting the Patriot Act, the Defense of Marriage Act, were not only not libertarian, they were anti-libertarian.
Bob Barr has a solid record of being authoritarian, the polar opposite of libertarian.
