"The puzzle that Tad Shull seeks to explain in this stimulating and informative study is the dramatic contrast between the Green parties of France and Germany. Although the German Grünen receive more scholarly attention, the little-studied French Verts have arguably had a greater impact on their country's politics. Explaining the two parties' different trajectories, Dr. Shull focuses on structural opportunities and constraints, highlighting the importance of Green Party strategy and the relationship to the larger, established center-left party. This book will be of great value to students of political parties and party systems, Green movements and West European politics." — Mark Kesselman, Columbia University "Professor Shull's book provides scholars a fresh view of ecological parties in Europe. It is extremely well written and it breaks new ground on this topic." — Sheldon Kamieniecki, University of Southern California"Tad Shull has provided a thoughtful, informative, and compelling account of Green parties and their role in European party systems. Redefining Red and Green is an important contribution to our understanding of emergent center-left politics, all the more timely with the formation of a governing Red-Green coalition in Germany." — Joel Krieger, Wellesley College
