This is fun. The Political Compass
I am:
Economic Left/Right: -0.12
Social Libertarian/Authoritarian: 2.4
On the chart, this puts me dead center right/left, and just a bit up from center towards Authoritarian. I'm fairly close to Kerry, actually.
Check the website and see where you fall, as well as famous people and the presidential hopefuls. Also, the Iconoclasts section is a great eye-opener!
