You can't really rank these countries on a right-left scale. The cultures and political climates are too diverse to compare.
Hmmm....I don't know. I admit that it's messy, but don't you think that if you break it down into economic, social, and foreign policy issues, you can make some comparisons? For example, wouldn't most people agree that the U.S. is more conservative than most other western countries in all three categories, or that France is to the left of Australia on both economics and foreign policy?
No some coutries have entire different ranking scales. In denmark as an eksample many people are progaymarriage and abortion, but they are at same time quate hostile to immigration and immigrants.
