So, some time ago I took Bryan C's "Libertarian Purity Quiz." (to paraphrase Jeff Foxworthy, if you care more about testing purity than about actually affecting policy in the world....you MIGHT be a Libertarian). As I noted then, I got a 54.
Took the test again. This time, 66. George Bush, you did this to me. I have jumped up more than 10 "purity percentiles" in a little less than four years.
