It was one of many promises. Governments break election promises. This is not unique. And this promise would've been a colossal waste of political time. All goes well in Canada. The 39% you refer to didn't all vote Liberal "because" of electoral reform. I am certain that the number of those who insist that electoral reform should be a priority is far, far far lower than its supporters say it is. This government was elected primarily because the much-hated Stephen Harper wasn't its leader - not because of a demand for electoral reform..
