Here is a test to see if you are a libertarian. The scale is from 0 (good) to 160 (very libertarian).
I got 8, and I will be very impressed by anyone who can beat that. If you get more than about 30 then I am afraid you have to join the Liberal Democrats (Orange Book flavour) or suffer some other equally unpleasant fate. As ever, record your scores in the comments (Tim has the current record of 7, you are not allowed to cheat in order to try and beat that).
