Funny how you can pretty much predict someone's views on an issue by observing what would be in their own personal best interest.  Mr Broadbent has done very well for himself in life as a politician aligned with a radical socialist party and, lo and behold, he doesn't like the fact that "first past the post", which clearly is not good for the NDP (or, for that matter, any other splinter group from Muslim Brotherhood to white supremacists), is staying put.  The last thing Canada needs in tumultuous times like today is a balkanized Parliament (this is a democracy, every 4 years we get to throw out or keep what we've got, so zero threat of autocracy), but Mr Broadbent is not interested in what's good for Canada, he's interested in what's good for the NDP.
