Book excerpt: This ground-breaking collection of writings explores how progressive third parties in the U.S. can become more electorally successful and politically influential. It is the only recently published book that focuses exclusively on how such parties may advance. Their rise may be essential to countering the powerful, growing sway of wealth within the two major American parties, and to creating a more just, democratic United States. Contributors include key participants in and observers of the U.S. left third party movement. Nearly all have previously authored books or articles on progressive politics. Many have led effective left third party efforts, and some have held elected office on behalf of a progressive third party. Together the writers reflect on a wide range of relevant parties—including the Green Party, the Vermont Progressive Party, the Labor Party, the Working Families Party, Socialist Alternative, and potential new parties on the American left. The authors highlight a variety of strategies and conditions that may facilitate electoral breakthroughs by such parties and their candidates. Overall, the collection suggests that U.S. progressive third parties may make more headway if they thoughtfully combine their idealism and sense of urgency with a flexible, pragmatic approach to gaining power.
