How do campaign fundraisers tap into potential donors' motivations? Exploring three decades of historical data and also drawing extensively on the insights of contemporary campaign directors and consultants, Bertram Johnson makes sense of why people give and considers what this means for the campaign finance system, and the quality of representation, in the United States.
