So the Liberals are favouring a system that benefits them. 

The NDP is 'virtuously' favouring a system that benefits them. 

The Conservatives are demanding a referendum hoping, like all the other referendums on the subject, it will fail and we'll keep the existing system that benefits them. 

Please, if nothing else, keep it simple. 

And if it takes you more than two minutes to explain how it is going to work, it is too complicated.

And I really couldn't care less whether there is a referendum on it or not.
