That was the problem the first go-around, the Liberals favoured ranked ballot but would consider STV, the NDP wouldn't support anything other than MMP, the CPC wouldn't support any change, and the Bloc just wanted to play spoiler. The Liberals were in a minority on the committee. The only system they could get agreement on was MMP, which is what was recommended.

MMP is good for proportionality, but it can have issues with party lists, members not tied to geographic areas can be difficult to remove, and responsibility for geographic areas is shared, making it easier to dodge. The biggest drawback is explaining the system to a general public who only have known a one vote, one member, one riding system. Ranked or STV are much easier to explain and the current riding system doesn't need to change.

Anyway, the Bloc and CPC were going to campaign hard on calling any change a Liberal power grab. Internal polling (not the dog and pony show web poll) showed that most voters didn't care about the issue, but the "Liberal Power Grab" would gain traction. With the CPC promising to roll back any changes, the whole thing looked more and more like an effort in futility.

In the end, they decided to take their lumps and move on. After all the heat they took for trying, as far as the Liberals are concerned, the issue is dead.

Right now we have a system where a party can have a majority of the seats with as little as 35% of the vote (and technically even less) and you're saying it's worse when the parties have to form alliancess so they represent a majority of the vote in order to hold the reigns?

It's funny because at the moment we are moving towards elections that will put our own right wing/social conservative party in power with a majority while about 60% of the population votes center left to center right, with a proportional system the NDP and Liberals would just form an alliance and represent the majority of the population.
