Coming out of the 2000 Canadian federal election, the dominance of the Liberal Party seemed assured. By 2011 the situation had completely reversed: the Liberals suffered a crushing defeat, failing even to become the official opposition and recording their lowest ever share of the vote. Dominance and Decline provides a comprehensive, comparative account of Canadian election outcomes from 2000 through to 2008. The book explores the meaning of those outcomes within the context of the larger changes that have marked Canada’s party system since 1988. It also shows how these trends were consistent with the outcome of the 2011 federal election. Throughout the book a variety of voting theories are revisited and reassessed in light of this analysis.
