From Daily Kos and the blogosphere to the rise of Twitter and Facebook, politics and new media have co-existed and evolved in rapid succession. At a time of collapse of the political center, extreme income inequality, rapidly changing demography, and the emergence of a second-generation online progressive movement fueled by e-mail and social media, ours is a period of realignment. This book brings a unique mix of academic and practitioner expertise and draws on unique data to consider how new and old media technologies are mixing with combustible politics to determine the shape of the emerging political era.
