This is a fascinating inside look at one aspect of the Bernie Sanders run for the Democratic nomination for President. It doesn't pretend to analyse the whole campaign strategy, simply focussing on the part of the campaign that the authors were part of - the attempt to recruit and use the energy of the thousands of volunteers who responded to Bernie Sander's candidacy.
The authors show how their volunteer engagement was built, often making it up as they took each step, often in response to the next challenge.
The book is refreshing, as it doesn't try to contrast and criticise the other campaigning techniques used by the alternative candidates on either left or right. Rather the book offers an reflection on what grassroots organising can offer a mainstream campaign. As they suggest, next time hopefully a candidate considering a run for the nomination will learn these lessons and implement them at an earlier stage, and maybe get further.
But the book has a larger context than just the Sanders campaign. It suggests 22 'rules' any campaign seeking to harness volunteer support can apply. It is a useful contribution to the toolbox any community organiser should have. The penultimate chapter reflects on the various social media and open source software apps and tools that they used, but as Zack Exley notes, by the time the next campaign starts the tools will have developed and there will be new combinations to try.
Although set within the specific constraints of a presidential nomination campaign, the interesting challenge for the authors and readers, is how these rules will translate into different settings. How successfully they can be used in non-US politics is also of interest. While crowdfunding is a growing means of raising money for U.K. political campaigns, some of the wider lessons of volunteer engagement are still to be tried.
