In 2011, Canada's New Democratic Party stunned voters with its breakthrough emergence as Canada's Official Opposition. After near collapse in the 1993 election, how did this distant third-comer manage to triple the seats won by its Liberal rivals and take more than three-quarters of Quebec ridings? "Reviving Social Democracy"'s early chapters - on the party's emergence in the 1960s, its presence in Quebec, and the Jack Layton factor - pave the road for insightful analysis of issues such as political modernization, changing ideology, voter profile, and policy formation that played a significant role in driving the "orange crush" phenomenon. Using sources such as federal election voter surveys, party member surveys, and party manifestos, contributors to this volume add deep analysis to a topic freshly ripe for scholarly debate. In the final section, they explore such future-facing questions as the prospects of party mergers and the challenges of maintaining support in the long term.This perceptive analysis of the political fortunes of the NDP not only adds to our understanding of its role within the Canadian party system but also positions us within the political landscape as we move towards the next election.
