No electoral system is perfect. But PR has a far worse track record than FPTP over the last century. How did Hitler rise to power in 1933: PR system. Why can't Israel fend off its own radical minority elements and move closer to real peace with its neighbours: nearly pure PR in the Knesset. Where are the right wing parties making the biggest inroads in Europe? The PR systems, including, most likely, the Netherlands soon. Italy has had over 60 governments since WWII: PR. The European PIIGS which all got into severe economic crisis over the last decade: ALL PR. Russia: PR with high threshold locks Putinesque parties in the Duma. Wonder what keeps Erdogan in power in Turkey: a PR system with a high threshold. I've studied electoral systems for years, and all the supposed benefits of PR overlook the empirical reality of PR's institutional effects on politics. For a federal Canada, it would be a disaster.
