You may have already seen this Nation story about libertarians and the Ron Paul campaign. I just want to highlight one sentence in it:
When Lindsey says that Paul "comes from a different part of the libertarian universe than I do," he's referring to the libertarian version of the Trotsky/Lenin split, which opened up in the early 1980s and continues to echo through libertarianism today.
The Trotsky/Lenin split? Yes, we all have our little brain farts, but come on. When you can't even count on The Nation to get this stuff straight, you know Marxism is dead.
