This book contains 18 different articles that deal with leftist governments in Latin America. The introduction and conclusion provide interesting arguments with regards to the causes that led many countries in the region to elect left parties in the 2000s. The authors also provide a typology to classify left parties in the region: the PT in Brazil or Frente Amplio in Uruguay are very different from the PJ in Argentina or MAS in Bolivia. The authors argue that these differences are the product of different historical legacies (for example, the PT and FA were created in the 1970s-80s, during these countries' Bureaucratic Authoritarian regimes, while MAS emerged as a social movement at the end of the 1990s). The rest of the chapters deal with different important topics. For example, the chapter by David Samuels and Jason Ross Arnold explores public opinion and the left (are Latin American voters really leftist?) and other chapters are case studies of each of the different national experiences. If you want to understand the left in Latin America this book (plus the one edited by Weyland, Madrid and Hunter) is a good way to start.
The book is great, but whatever you do, do not buy the Kindle version. It was poorly made, the table of contents does not comprise of the chapters, making navigation inside the book a lot more complicated than it has to be. :(
