If we did decide to go to some kind of mixed member proportional system, for example, it's seems to me that one of the really important questions would be the composition of the lists and how exactly you institute some kind of open list. So maybe you've got the most closed model where it would be the party leadership that decides who's on the list; or you've maybe got a model where voters can interject because they can kind of vote within that list for candidates.
I just wonder, Professor Milner and Mr. Himelfarb, if you want to talk a little more about what you imagine might be a good model for list choice in Canada.
