Ian Urquart [a-doy, I need to read bylines more closely...] at least, isn't making up wholesale fantasies of dhimmitude or anything. But he persists, like so many journalists, in worrying about fringe parties. Apparently, journalism now requires that we narrow the bounds of acceptable politics, not expand it.
But what's really annoying about this trope -- not just when Walkom uses it, but always -- is that it's not simply the size of a coalition that matters, but the stability. So a minority government has a very strong interest in seeking the cooperation of a large, moderate party with a number of seats. Tory's first attempt if he wanted a coalition government could very well be the Liberals, like the current government in Germany.
Oh, and on that note, it's incredibly aggravating that Ontario's media persist in pretending that Germany doesn't exist for the purposes of this discussion. Only Andrew Coyne is busy pointing out the comparison, because it looks really, really good.
