What separates campaigns that win from those that don’t? At any given moment, there are hundreds of campaigns under way that seek to persuade citizens or decision makers to think, act, or vote in a certain way. Engagement Organizing shows how to combine old-school people power with new digital tools and data to win campaigns today. Over a dozen case studies from NGOs, unions, and electoral campaigns highlight this work in practice. At a time of growing concern about what the future holds, this book is an indispensable guide for seasoned campaigners as well as those just getting started, who want to apply the principles of engagement organizing to their own campaigns.
