If Trudeau has said NO to MMP then it’s time to explore alternative mixes of proportional representation and a majoritarian system. I’d like to proffer the Alternative Mixed Proportional system.
It’d have lots of 4-seat ridings and one at-large seat. The at-large seat would use the Alternative vote. The alternative vote would also be used for one out of each of the 4 seats in every riding. The other three seats would be determined with the simplest, purest proportional representation system possible s.t. there being only 3 seats: Largest Remainder with a Hare quota.
3-seat LR Hare is very similar to First Past the Post, which is 1-seat LR Hare. It has one vote per voter and one candidate per party. A common outcome would be for the top 3 parties/candidates to win one seat each. However the locally top party can win 2 seats if their candidate’s percent of the valid votes is 33.3% greater than the 3rd place candidate’s percent of the votes. In that case, the second seat would be held by a vice-candidate. It’s unlikely that a party would win 3 seats, as that would require for the top candidate to beat the 2nd place candidate by more than 66.67% of the vote.
Here’s some concrete examples:If the percents were 40:30:20:10 then the top 3 would win one seat each. If the percents were 50:35:10:5 then the top party would win 2 seats, since 50-10>33.3. If they were 80-10-8-2 then the top party would win 3 seats.
In Canada, AMP would give Trudeau/LP one-fourth plus of what they want and overall tend to let two outcomes happen if there is a dominant party: it’d either have a majority or it’d be the bigger party in a coalition. But to get the majority, it would need to win quite a few 2 out of 3 seats in a 3-seat LR Hare election and that would require them to be attentive to the issues of local minority groups, like First Nations people. This would not be as true if only the Alternative Vote were in use.
So no doubt Canada needs electoral reform, but there are true hybrid systems that are neither purely proportional nor purely majoritarian and it seems that is what you should focus on….
