This site asks a bunch of different questions and then plots you on an x-y axis.
I am:
Economic Left/Right: -4.88
Social Libertarian/Authoritarian: -5.85
meaning that on a scale of 1-10 for liberalism, i'm about a 5 and about a 6 on a scale of 1-10 for libertarianism.
Which means I'm more a libertarian than a leftist. Hmmmm....
