Libertarian presidential candidate Bob Barr--and proverbial skunk at the GOP garden party--made an appearance on Fox News yesterday:

"What's wrong with John McCain is symptomatic of what's wrong with the Republican Party in these first years of the 21st century," said Barr, a former Republican congressman from Georgia. "They talk one thing but do something different, and that's become very obvious to the American people."

Libertarians are known to be a purist bunch, which is why it must have been a tad awkward when Chris Wallace inquired about Barr's own inconsistencies:

In the interview, the former lawmaker was pushed on his own record, with host Chris Wallace pointing out that Barr had supported the Patriot Act and backed the Iraq war.

Barr's answer was dicey at best:

"I was wrong with regard to the Patriot Act, entrusting the administration with its assurances that the act would not be used and abused," he said. "And I certainly was wrong, along with a lot of others in the Congress, who now realize that their vote in support of military operations in Iraq was not what the administration intended. They intended to occupy the country even though they didn't tell us or the American people that at the time."

Translation: "Well, I basically trusted the government at the time." Not exactly music to Libertarian ears--many of which, it's pretty safe to bet, are still longing for Ron Paul.
