If I might say so, Ed, here's the problem. There are a number of problems, I believe, but one problem is this: as you would know very well, the phrasing of that Liberal election promise, “This will be the last election conducted under first past the post”, was taken word for word from an NDP opposition day motion from December 2014. The NDP motion went on to specifically mention proportional representation. It may even have said MMP, but I can't remember now.
On August 29th, 2016. See this statement in context.
