After a self-assured John F. Kennedy bested a visibly shaky Richard Nixon in their famous 1960 debates, political television, it was said, would henceforth determine elections. Today, many claim the Internet will be the latest medium to revolutionize electoral politics. Candidates investheavily in web and email campaigns to reach prospective voters, as well as to communicate with journalists, potential donors, and political activists. Do these efforts influence voters, expand democracy, increase the coverage of political issues, or mobilize a shrinking and apathetic electorate? Campaigning Online answers these questions by looking at how candidates present themselves online and how voters respond to their efforts-including whether voters learn from candidates' websites and whether voters' views are affected by what they see. Although the Internet will not lead to arevolution in democracy, it will, Bimber and Davis argue, have consequences: reinforcing messages, mobilizing activists, and strengthening partisans' views. Reporting on a wealth of new data drawn from national and state-wide surveys, laboratory experiments, interviews with campaign staff, andanalysis of web sites themselves, Campaigning Online draws the most complete picture of the role of campaign websites in American elections to date.
