the liberals did not propose a proportional representation system, or an mmp system, but an av - that is, ranked ballots.

the ndp, however, has long proposed proportional representation - and lost several referenda on the topic.

sadly, many journalists in the media were unable to understand the differences in the party proposals, and this created a confused electorate that thought voting liberal would lead to pr. but, that was never actually promoted or presented in any remote way by anybody in the liberal party.
