This puts me pretty far away from any of the British parties, save the Green party. On further examination, it puts me pretty far away from any political party, as the vast majority of (British and US) politicians are in the upper right quadrant. (Nelson Mandela is closest to my alignment. Also in my quadrant: the Dalai Lama and Dennis Kucinich.) I’d always argued against the “there’s no difference in the major parties” line, but there seems to be more to it than I’d realized.
The site also plots how different parties have changed their alignment over time. (Almost always up and right, so progressively farther away from me.) Interesting stuff, even if a bit depressing.
