Bob Barr, Libertarian for President

Top Republicans fear Barr could be the spoiler, the Ralph Nader, for McCain. But Bob Barr says the GOP has spoiled its own fate.

The man who once led the charge to impeach Bill Clinton now tears into George Bush, the Iraq War, the Patriot Act, and a whole lot more.

Guests:

Bob Barr, former Republican congressman from Georgia. He is the 2008 Libertarian Party nominee for president.
