Book excerpt: Following on from the critically acclaimed 'Road to Referendum', Iain Macwhirter casts his expert eye over the longest and highest profile campaign in Scottish political history. Looking to the future, the book explores the issues that made and broke the campaign, the relationship between culture and social media to referendum politics, the biased reporting in the twilight of media and broadcasting, the future of nationalism and federalism, and Salmond's 'last stand'.
