I very much doubt there is anything the Liberals can do to stop the bleeding and after the CBC interview and the debates I have no faith in Ignatieff whatsoever, but here is what I would do.
English Canada: The Liberals have lost the Francophone vote. There no hope of getting them back. So there is no need to pander to them anymore. Talk about the Clarity Act and its importance. Characterize Stephen Harper as once having been an Alberta separatist for having written the Firewall letter and Separation Alberta Style and blast Jack Layton as having abandoning the Clarity Act and supporting the extension of bill 101.
French Canada: Talk about social issues. Harper's Achilles heel has always been his social conservative base and the Liberals have been stupid not to attack it. At the this point in time the Liberals have to drop a bomb shell. I have always favored legalizing marijuana, but think it is too late for that now and doubt Ignatieff has the ability to make his lunch let alone the case. Maybe he could suggest that he would be willing to entertain the idea. However, Liberals definitely need to talk about legalizing euthanasia.
