To tweet or not to tweet: Exploring the determinants of early adoption of Twitter by House members in the 111th Congress

The adoption of communication forms like Twitter presents students of congressional behavior an interesting case to examine the intersection of technology and politics. Twitter represents a social media venue that provides an immediate and direct link between the Member of Congress (MC) and constituents, which entails a benefit and a potential risk. In this paper, I examine Twitter use in the 111th Congress in order to better understand congressional early adoption of new technology. The primary question addressed is what systematic determinants shape the decision to adopt Twitter as a component of an MC's media strategy. Using data collected from MC Twitter accounts and the 2008 congressional election, I find partisan, cohort, and ideological determinants on early Twitter adoption. Republicans are more likely to use Twitter even in multivariate analysis; ideological extremism influences the use of Twitter. In contrast to past technologies, district demographics have no systematic effect on the early adoption of Twitter.
