Maybe this is the right approach. Certainly Stephen Harper is not very popular in Quebec so speaking out might hurt federalism. Still, even if he is silent I strongly suspect he is concerned - at least I hope so!
Prime Minister Stephen Harper has told his cabinet and caucus to stay out of the campaign. That hands-off decree is in stark contrast, for example, to the Alberta provincial election last spring, when a number of federal cabinet ministers openly endorsed the fledgling Wild Rose Party.
