Those who know me, know I'm a fan of the "Political Compass", which is a fun little test working on the premise there are two axes to the political spectrum - left/right (essentially an economic and welfare axis) and liberal/conservative (a more personal/societal axis).
Check out
www.politicalcompass.org or a similar discussion on wikipedia at
http://en.wikipedia.org/wiki/Political_spectrum (which shows that the political compass is actually based on a proper theory, not some BS).
