Interesting graph. It places virtually the entirety of American politics dramatically to the right of virtually all of Europe.
I think it would make more sense if there were two graphs. One for social and one for economic. Maybe a third for foreign policy. I think things are more complicated than we make them out to be... I really think most Americans are more with the Ron Paul, Dennis Kucinich, Mike Gravel area when it comes to social issues. I wish some "mainstream" dems would realize that, it'd make it a lot easier to support them for me.
