Challenge of Direct Democracy [PDF ebook] 
The 1992 Canadian Referendum

Based on extensive surveys conducted during and after the campaign, The Challenge of Direct Democracy is a comprehensive investigation of voter opinion, intention, perception, and behaviour in a referendum. The authors investigate voters’ responses to arguments for and against the Accord, examine how well informed voters were, and explore a variety of explanations to account for the negative result.
