this is the right article for the topic, but i just want to add a sobering thought of my own: the question of whether trudeau's senate amendments will outlive him or not reduces to how responsibly they abuse their power (for any use of power, in context, is an abuse of it). i'm convinced that this is a kind of an insane ploy to let him promise the sky at election time and get shot down between elections, and insofar as that is true it is just a waste of everybody's time. but, no future government is going to be obligated to entertain the whims and fancies of a senate full of unelected independents that was appointed as some kind of twisted joke.
undoing this mess that he's made of the senate may very well be the first thing that his successor does - even or perhaps especially if that successor is a liberal.
