This is like a priest calling the Pope a Catholic: The Libertarian Party sent an email to its supporters on behalf of its nominee for president, Bob Barr, criticizing the Democratic Party's nominee-apparent for vice-president, Joe Biden. According to the email:
"There isn’t much to Biden that the public doesn’t already know. He’s a career Senator with more than 30-year history of being a "Congress critter." Biden is not only a part of the political establishment, he’s a senior member of it! In fact, Biden has only spent four years working in the private sector after graduating from college."
The email conveniently omits the fact that its own candidate, Bob Barr, worked 8 years for the CIA, 4 years as a federal prosecutor, 8 years as a "Congress critter", and the only reason he left Congress was because he was forcibly retired by his own constituents.
