Someone asked:

I don’t understand how AV “institutionalizes strategic voting” – if one is able to rank their preferences there is never a need to “vote strategically”… you put the candidate you would prefer most as your first choice, and your second as your second choice, and so on. There is no need to vote any differently than your real preferences because your vote continues to have an impact regardless of how other people in your riding vote.

How To Vote cards I look to Australia for an example of “institutionalized” strategic voting. Their House of Representatives is elected using Alternative Vote; during the election parties hand out “How to vote” cards to tell people how to rank their ballots to ensure their party has the best chance of winning the election by giving lower rankings to candidates in particular ridings that might win on the second or third round of counting. Ranked ballots in single member ridings just tend to weight results to a single party. Conservative voters tend to give 2^nd choice to a centre-right candidate, 3^rd to a centrist. Progressive voters tend to give 2^nd choice to a centre-left candidate, 3^rd to a centrist. Suddenly you have the centrist candidate (who got few first-ranked choices) winning on the second or third round of counting. With single-member ridings this happens again and again in each riding. Centrist parties really like Alternative Vote in Single Member Ridings. To ensure that all voters along the political spectrum get fair representation, ranked ballots need to be combined with multi-member ridings. Single Transferable Vote does this, and to a lesser extend Mixed Member Proportional. In either case, the more members that are elected in a single electoral district, the better the proportionality, but larger ridings result in less local, geographical representation. In speaking with hundreds of people at Fair Vote information tables over the last 12 years, I find that people really value local geographic representation. So Mixed Member Proportional is a good compromise between proportionality and local representation.
Mixed Member Proportional Representation ballot The Green Party of Canada formally adopted Mixed Member Proportional as the preferred voting system in a policy meeting at the Special General Meeting in December 2016. That policy also states that if a referendum to change the voting system is held, either it should not include non-proportional systems in the question (so Mixed Member Proportional, Single Transferable Vote, maybe Dual Member Proportional, but not First Past The Post or Alternative Vote), or the referendum should be held only after at least two consecutive elections using a proportional voting system. –Bob.
