Who Donates to Campaigns? examines data on donors to the 2008 and 2012 presidential election campaigns to demonstrate who is donating and how the internet and campaign finance law have contributed to significant change. This book will be of value to students, scholars, campaign professionals, and journalists and anyone interested in US campaign and elections. 'Magleby, Goodliffe, and Olsen have made a major advance in our understanding of donors and the effect of their donations in modern electoral campaigns in America ? The result is a massively important advance in our understanding of who donates and why they do, increasingly critical questions in today's campaign environment.'
