There is also the issue of whether referendums should be held simultaneously with federal elections, or not, as a matter of policy, as opposed to just happenstance. If I recall correctly--and I don't have the greatest memory--there have been pretty strong arguments on both sides. One is that it makes all the sense in the world for a small country like this to be able to do it at the same time. It's more efficient and it saves money. The other argument is that if you do them both at the same time, you're going to skew one of the two results because either the referendum question or the general election will become paramount in the minds of the parties and in the media, and it wouldn't do justice to either one. You need to keep them separate.
You probably touched on it, but could you again state your thinking on that issue?
