I’m writing from the other side of the planet, but there are enough Oz-related links to offer some thoughts on the Canadian election result.
First, taken in conjunction with the recent removal of Australian Prime Minister Tony Abbott, this is a big win for the planet. Abbott and Harper were the only two world leaders who were clearly climate denialists (despite some official denial-denialism) and now they are both gone. That leaves only the US Republican Party as a serious political force dominated by denial (of course, a big “only”). The chance for a decent agreement coming out of the Paris conference in December has improved significantly
Second, as the UK election also showed, the combination of multiple parties and First Past the Post voting is highly unpredictable. If things had shaken out a little differently, Harper might have managed it back into some kind of minority government, or we could be seeing the NDP rather than the Liberals winning on the basis of strategic voting. Applying this to the UK example, the idea that Cameron’s victory was in some sense inevitable is fallacious. Had a few things gone differently, we could all be talking about the mysterious appeal of Ed Miliband.
Third, the supposed dark magic of Oz spinmeister Lynton Crosby did Harper no good. If anything, Crosby’s dog whistle strategy motivated the majority to vote strategically against Harper. But I suspect that people like Crosby are better at selling themselves to politicians than at selling politicians to the public.
