It isn't just Stephen Harper's uniting of the right. I've never been troubled by the fact that parliamentary majorities are most always “manufactured”, to use the term of art in academe. “False majorities” is a partisan label, I think.
The facts that didn't seem to fit in 2001 concerned the ability of the party system to provide a reasonably healthy level of competition for office. I underestimated the ability of the political right to get its act together. And in 2011 and 2015, although I wasn't advocating one way or the other, I underestimated the capacity of the centre-left to get its act together.
