The enemy of my enemy is my friend
Colby Cosh advances the possibility of a Liberal-Tory coalition government to keep the Bloc out of power if we have two stalemate elections in a row.
Colby is wise, and it is fair to say that a shotgun marriage would work. Nevertheless, I don't think that the Bloc is dangerous enough to make the scenraio plausible for any length of time. What the Liberals would do is package some goodies for Quebec and say to voters there "You want this? Give us a majority government."
I think a Tory-Bloc coalition would make more sense, if the Bloc would be willing to put up with some conservatism in order to get a lot of political decentralization. (Quebec shouldn't mind if all the provinces start getting their BNA Act-granted powers back instead instead of just Quebec, right?)
Harper will be able to say, "Look, we might be conservative, but all the other parties like centralized federal government and we are the only ones willing to even consider provincial rights. Deal with it."
I guess it depends on what the Bloc wants more: provincial rights or socialism.
