I discovered this interesting chart for the US Primaries 2008 while perusing Notes from underground. It was created by The Political Compass. Sadly, according to the criteria of the Political Compass website, the only two candidates who show up as non-authoritarian and left of center are the two that hadn’t a ghost of a chance, Dennis Kucinich and Mike Gravel. Clearly, the perspective here is not that of the American Mainstream Media, but may it not in fact be realistic from some perspectives, perhaps that in parts of Europe?
The website also provides a test for a person to compute where she/he stands on the Left to Right, Authoritarian to Libertarian scale. I took the test and found that I fell in the lower left quadrant, that of the leftist libertarian. The questions are general enough so that if you feel like putting in a little bias you can maybe move yourself around a little on the chart, or even perhaps a lot, depending on how much you might cheat.
