The problem is that we don't have a lot of cases. We really just have Australia. That's why I was bringing in Alberta and Manitoba. It provides a useful other set of cases that give us some other evidence. I don't think there's anything that would preclude other parties from doing well.
The thing that I think we have to remember is that the other parties would adjust their behaviour in response to the system. My observation is that the Conservatives very much tried to polarize themselves against the Liberals, NDP, and Green Party. That's not a very good strategy under an AV system. You want to reach out for second preferences. Would they have campaigned that way? Would they have structured the government that way over the last...? I suspect not, if the incentives were a little bit different. It's very, very hard to predict. This is based on how they behaved this way, so, if you look at the polling data, there weren't a lot of party second preferences. That was a deliberate strategy they took. They might have behaved differently.
