I can guarantee that if "vote splitting" and "strategic voting" was hurting conservatives and helping the NDP they'd be champions of election reform and the NDP would be talking about "sore losers" and how expensive and confusing better systems are. This is why we'll never see it, because it generally only helps smaller parties not in power. Good for democracy, bad for those in power. The reforms demanded and criticisms made to the government in power by the opposition have a strange way of suddenly reversing when the roles are switched.
I don't recall the PC and Reform Party, or even the Federal Liberal Party blaming their problems on the system when they finished in third place.
