New in paperback. Hardcover was published in 2014. Since 2010, the judiciary has decided that corporations and labor unions may freely spend in American elections, and that so-called "Super PACs" can accept unlimited contributions from private citizens for the purpose of buying election advertising. Using campaign finance data, election returns, advertising archives, a public opinion survey, and interviews with congressional candidates in the 2012 election, this book provides unprecedented insight into the behavior of these organizations, and how they affect public opinion and voting behavior.
