I used to believe the NDP and its leaders like Mr. Broadbent were simply self-serving by wanting to go to a PR system.  After 50 years of ideas that did not appeal to a sufficient number of Canadians for the NDP to achieve electoral success nationally, they decided the only way to win would be not to change their message, but to change the rules.  I will note the hypocrisy inherent of the NDP never pushing for PR and legislating for the same without a referendum in provinces where they do regularly win majorities.  Apparently first-past-the-post works fine in those electoral situations.
Now however, I believe Mr. Broadbent has gone past the point of being self-serving to being evil .  You need to change the system so Canadians can never elect someone Mr. Broadbent disapproves of.  150 years of Canadians electing parties and leaders of the broad middle-of-the-road are not enough.   (to be continued).
