A Comparison of Conventional and Internet Political Mobilization

Abstract

The high cost of contacting individuals encourages mobilizing institutions to maximize resources by targeting those most likely to effectively respond, resulting in stimulation of the politically engaged, civically skilled, and socioeconomically advantaged. By dramatically reducing communication costs, the Internet should eliminate the underpinning of this “rational prospecting.” However, because most e-mail addresses are not available in public directories and cultural norms make sending unsolicited e-mail politically risky, individuals generally must provide their e-mail address before receiving e-mail messages from political organizations. Online mobilization campaigns should disproportionately contact those with the political motivation and technical ability to submit their e-mail. The author tests these expectations about online political mobilization using a probability sample survey. Although most of the long-standing determinants of offline political mobilization fail to predict online mobilization, political interest and Internet skills powerfully determine online mobilization. However, because socioeconomic status, civic skills, and political interest directly predict online skills, these factors indirectly influence the likelihood of online mobilization.
