For the record: "If we work hard and stay optimistic, we will put forward an irresistible alternative to the Conservatives 30 months from now. Irresistible not because it is Liberal, but because it will be 100 per cent, undeniably Canadian. It won't be easy ... Hope, my friends, yes. Always hope. But more than that. Hope and hard work."
