This could be dangerous evidence in establishment hands. I can imagine them now, "See! Look at the chart: Ron Paul is not a true conservative! He's a radical libertarian!!"
http://www.issues2000.org/default.htm <<<Good website. Includes votes/quotes/etc. on individual positions. click on the candidate and it will have a huge list. Go all the way to the bottom has where they are at on the chart (not the political quiz though, but as good as you are going to get).
Ron should probably be higher in the libertarian quadrant, since OnTheIssues scores him as being anti-free trade, but whatevs. Still is a good general idea of the difference between the candidates.
