That one is not the Nolan Chart. It is from OnTheIssues.org and is narrower in its criteria (doesn’t go to the extremes right or left but keeps it to US political landscape.)
I get that, but on the face of it.. it is wrong. We know because when we try to plot out the "Conservatives" we find three sub-groups, Socal, Economic and Security conservatives. How is the plotted on this chart? Name anything about a Libertarian that would put them at 100% matching the Communists on one side and laissez-faire Capitalists on the other???
In my world, 100% personal freedom and 100% economic freedom is not Libertarian, its Anarchist. And what self-respecting Communist will tolerate any personal freedom??? The whole thing is nuts. Ala, the folks banning kids bringing their own lunch to school.
But this also means that folks placing politicians on charts like this are lying to us..
Now, the OnTheIssues site they point to www.self-gov.org as the source of this chart.. but this is dead now.. and instead it points to http://www.theadvocates.org/ and rather than self-government, this site is a crypto-Ron Paul/Libertarian site with a extremely tainted quiz to convince people they are in-fact libertarians. So, anyone using this chart is deceiving anyone reading it.. or don't care whether the chart is useful or crap.. either makes me say.. pile of stinking poo.
