Chris Lightfoot has done another version of his political survey, which extracts axes from the answers given by survey respondents. The axes for the last version were economic left/right and pragmatic vs idealistic; this one divides people into "hanging / flogging Eurosceptics" vs "rehabilitation internationalists" (the most significant axis), and "free market pro war" vs "socialist anti-war". More information on the survey methodlogy can be found here.
In addition to giving handy cartesian coordinates, it also compares your scores with those of major UK political parties and newspapers, as well as by age and location. Unfortunately, the questions are fairly UK-specific, so I won't be doing a graph of this one.
