^ Why do you say there will be no strategic voting? That sounds like wishful thinking to me.
In STV you have no reason to ever vote for someone you like less higher than someone you like more (well you could if you want to be irrational). Right now Greens are told they have to NDP or they will cause the election of the Liberals, the same for BC Conservatives. In STV there is no fear of 'splitting' the vote.
There is no wishful thinking involved, all preferential balloting systems remove and ability to strategically vote.
