It is a fair observation that the federal Liberals' discussion of a ranked preferential ballot to replace the current plurality electoral system, popularly known as first-past-the-post, is a proposal that likely favours their party. What should also be acknowledged is that the other parties are also pushing proposals that favour their interests, too.
The current system was inherited from the British at Confederation, and dates back to a time when there were only two significant political party alternatives in most districts. In such a world, the system made a good deal of sense and typically elected members with a majority of the votes cast.
