Tweeting to Power is the most ambitious and well-researched study of social media's political consequences to date. Using an impressive array of qualitative and quantitative data, Gainous and Wagner systematically track how Twitter and Facebook are influencing Congress, political parties and the American public. This book is much more than a narrow study of social media, however. By situating their evidence in long-standing theoretical debates, Gainous and Wagner tackle more fundamental questions about the functioning of American democracy in the age of the internet. Tweeting to Power is essential reading for anyone interested in technology's impact on election campaigns, political communication and public opinion.
