Arnold Kling isn’t referring specifically to Quebec, but he might as well be:
The problem with physical secession is that it is very difficult to achieve critical mass. There is probably not much overlap between the people you want to live with and the people who want to choose your particular form of government. The vast majority of us put up with government we dislike in order to live in proximity to people with whom we want to work and play.
I can’t think of a better way to encapsulate the fundamental problem at the heart of the PQ’s mandate to be both the chief promoter of an independent Quebec as well as its natural governing party.
