essentially, which is why i've always been amazed by the tension between anarchists and libertarians. it amazes me to this day that most anarchists vote w/ the left and most libertarians vote w/ the right, despite the fact that they are the two remaining bastions of classic liberal thought and have more in common w/ each other than they do w/ the rest of the dems and reps.
Perhaps the average self-described anarchist looks for personal freedoms, while a libertarian generally wants economic freedom and just happens to be less controlling about social freedoms than most republicans? I know I would fit this description. Apparently I'm the only person here that would vote for McCain, out of the ones listed.
In all fairness, the broad groups generally do dislike their extreme sections.
