Openness and transparency is an uphill battle as partisan comments here and in the commons would illustrate. I suspect the same thing happened to our PM’s predecessor. They both started out with good intentions but then the daily grind of abuse (in these pages, remember “tubby” or,  more recently, “junior”) starts to wear those good intentions down. Example: I would have thought that Ms.Ambrose would have been happy about 2 of 3 pipeline decisions but she didn’t have a good word to say. Mr.Mulcair, of course, was characteristically negative and Ms.May's packing for jail. . 
Harper finally must have decided it wasn’t worth worrying about anymore and, with a majority, stacked the senate, tried to stack the judiciary, ran through omnibus bills, etc. He took abuse but would have anyway.  Bottom line, folks, is we may not be stupid but the way we do government makes us look like we are and it makes our politicians eventually become hateful.
