The Bobo Files actually attributes this to McWar, but it more accurately applies to Bob Barr:
Well, I was really against all of that stuff before I was for it. But, now that I’m for it, you should vote for me anyway (before I’m against it again)
Bob Barr voted for the Patriot Act before he was against it. He was for illegal wars of conquest before he was against them. He was a drug war prosecutor before he was against the drug war. He worked for the CIA for nearly 10 years before he was against foreign interventionism. He was against abortion before he paid for one of his ex-wives to have one. He was a Democrat before he was a Republican Neocon, and all that before he was a “libertarian”.
The man cannot be trusted.
