James:  I don't think we'll ever move to a parliamentary system.  However, I do feel a movement for Preferential Voting actually has a chance for success.  Clearly the two major parties would oppose it "to the death."  However, there are increasing numbers of voters across the political continuum who would like to support a third party candidate w/o a) "throwing their vote away" and b) actually helping the "major" candidate who has the least in common with their third party candidate.  I think the more people understand the concept, the better they will like it.  regards, Gary
