Where's that then? Israel? (I *think* they operate a fairly pure form of PR. I don't think many, if any, other countries do.)
Uhm. The outcome wouldn't be any different regardless?
Plus not for nothing but PR is insanely bad for democracy. People already cry like babies that we don't elect our PM - imagine a world where you don't elect your MP either. Like we don't have enough problems with politicians who haven't actually worked in their lives.
Also it creates an environment where parties can stack members who agree with them which is incredibly dangerous.
