The fun point is this: Layton's party, the New Democratic Party [NDP], has more than half of its seats in .... Quebec. So, yes, the pandering may have worked, but now what? If there were a referendum and the 50% plus one rule played out, then Layton would find himself with less than half a party. Or he could try to become a leader in newly independent Quebec, not that he would win or anything. The irony is that his support of 50% plus one is suicidal politically in the extreme--if such a situation were to arise.
But, of course, if there were a referendum, I would count on the NDP supporting implementation of the Clarity Act--for its own survival, not out of principle. Not that it matters much really, since the Conservatives a majority in the Parliament where fifty percent plus one is also the rule.*
* I think--I have no real understanding of the Canadian constitution.Still, the idea that the NDP's fate would be held hostage by a Quebec separatist effort is actually quite amusing, as long as we do not get close to it in reality.
