To answer the second question first, I haven't had a chance to give my thoughts on a referendum yet, and I think that is a vital decision-making point going forward. I think that integrity and legitimacy are as much about the process as they are about the product, and democracy needs to be democratic. It seems absurd to me that this decision will be made any other way.
Some people said that multi-party consensus is efficient, but there are some systems that favour existing parties over parties that aren't even born yet or aren't really on the radar. Even multi-party consensus is a biased way of making a decision.
I think a lot of people are backing away from a referendum because they're afraid that they'll lose the referendum and we'll end up back where we started, not because they're philosophically against it. That's why I think it's important to come up with a system—which is what I've tried to do—that keeps some power in the hands of the voters, so that they don't get a one-shot deal at giving input on this issue. It's harder to do incremental electoral reform. I don't really see too many good options for doing it in pieces, but at some point you have decide which system we're going to have. The way to make it incremental is to continue to give them decision-making power on an ongoing basis.
I forget the first part of your question that I haven't answered yet.
