Proportional representation (PR) using the In Place method does not require the use of assigned multiple-member voting districts but uses the current riding districts. These interactive pages may be accessed with the Apple iPad in portrait mode.
Each voter has one vote, which produces a Party Elected List . This is essentially the 'normal' election results. In this model, this initial list will determine which party may get 'added seats'. This is an additional member system.
A party will get onto this list in one of two ways. Either by winning at least one seat, in the first-past-the-post way, or by gaining 1% (this is arbitrary) of the popular vote. For the Canadian election of 2015 the total of 17,569,634 votes gives a minimum threshold of 175,696 votes for a party to be added to this 'Party Elected List'.
The second major list is the Candidate Non-elected List (i.e. not first past the post). This list is sorted in descending order by number of votes received. For each row, an input Least Square Index is used to determine if this candidate will be an added seat in parliament, and changing the overall Least Square Index. There would be only a marginal increase in the number of parties, if at all. This model requires all candidates to be with a party, unless they choose the 'independent' option effectively removing them from this seat increase model.
Will this result in coalition governments? Not necessarily, but more inter-party compromise will be required. Most votes contribute to the election of a candidate so parties need to campaign in all districts, not just those where they perceive the most advantage. This fact in turn encourages parties to be more responsive to voters, producing a more 'balanced' ticket by nominating more women and minority candidates. Aware that their vote can make a difference, voters are more likely to make the effort to vote, and less likely to vote strategically.
This method produces a Resultant Party Elected List that is now more fully representative of the wishes of the electorate. All voters will be able to more easily consult their parliamentary representative as they are from their own constituency. All candidates will have a strong link to those who voted for them.
Note that the Least Square Index input value is critical to the number of seats that can be added. A value of -0.00 may give the best overall proportional representation, however, a smaller province may opt for, say -2.00, due to the higher cost of maintaining significant added seats.
