Without disagreeing with Anna, there is one other advantage. That is, we live in a conservative country in terms of our understanding of our electoral systems. We're reluctant to change. We've seen initiatives in other provinces fail, such as in British Columbia; there's here in Prince Edward Island; in New Brunswick it just went onto a shelf and didn't go anywhere. I actually worked on that commission.
One of the reasons is that the changes being proposed tend to be seen as very complicated and hard to understand. The one thing about a preferential ballot—I don't know that it mitigates what Anna said, but at least it has this value—is that people get it. If it were the case that a changed system adopting a preferential ballot happened, and people saw that the change was not so scary after all, then I think the next step of going to the more radical change would be a lot easier than to jump from where we are now to the radical change.
So it's at least that. It does not change, in any substantial way, the distribution of parties in the assemblies, which becomes a huge problem for people particularly supporting proportional representation, but it's at least a change that people can understand and are probably more willing to accept.
