This isn't exactly a personality test, but it does show your political affiliations based on the political compass model. Check it out, it's pretty cool.
The Political Compass
Economic: Left/Right: -3.38
Social: Libertarian/Authoritarian: -4.15
I am a leftist libertarian.
According to the website, my personal politics most resemble the Dalai Lama's. That's actually pretty awesome.
