Here is an entertaining little quiz to calibrate your political sensibilities. Besides the traditional economic left/right spectrum, this also includes the dimension of social authoritarian/libertarian. So you get placed on a 2-D graph. I know, I know: we all have other (un)lovely facets of our personalities not captured by this graph, but this seems to me at least a crude indicator of our political bearings as we often articulate them.
The quiz should take 10-15 minutes. Many questions require careful thought, so don't be in a rush to finish. Be sure to check out the company of luminaries you find yourself in (including music composers, famous leaders, and 2008 presidential candidates)! I have taken the quiz thrice over the last four years (first brought to my attention by VP), and I have hovered near the same spot -- from (-5.7, -5) four years ago, I landed at (-5.3, -5.6) today. How did you score and were you surprised?
