What are the most cost-effective ways to increase voter turnout? Whether the ambition is to win elections, promote civic engagement, or bolster the legitimacy of democratic institutions, this question is of enormous significance to those who run and study campaigns. Since the original edition appeared in 2004 Get Out the Vote has become the indispensable guide to understand how to mobilize voters. Combining information from their own extensive field research and the rapidly expanding number of studies conducted by a growing network of scholars and campaign consultants, Donald P. Green and Alan S. Gerber bring scientific rigor to the subject, challenging much of the conventional wisdom about what works and what doesn't in political campaigns. Updated to include the newest research and published in time for the 2024 election cycle, Get Out the Vote will again be the indispensable guide to voter mobilization for campaign managers, consultants, and activists across the political spectrum.
