About a decade ago, the hottest thing in political campaign was the Internet (Garecht, 2011). Political consultants and candidates touted the promise of the Web to change the mode of their campaign strategies. From fundraising to propagandizing, web-based campaigning overwhelmed the medium with political messages. Yet, with the sudden hype of Web 2.0 over the past few years, social media became the new hot medium for political campaigning. As the election season approaches, we are seeing an increasing amount of political messages streaming into social networking sites (SNS) such as Facebook, Twitter, and YouTube. Due to this trend, political parties are spending millions of dollars hiring social media experts to manage and monitor their appearances and respective messages on SNS. Nonetheless, how effective are SNS acting as a new medium for the transmission of these propaganda messages? Do SNS audience receive firsthand information from their political leaders, or through a group of active gatekeepers who screen information and only pass on items that would help others share their views on these sites (Baran & Davis, 2009)? According to an analysis of voters’ decision-making process during a 1940 presidential election campaign, Paul Lazersfeld and his team of researchers revealed evidence suggesting that the flow of mass communication is less direct than we supposed. Known as opinion leaders, this group of active gatekeepers maintains an important role in consuming and filtering propaganda messages on SNS. Drawing from the two-step flow theory of communication process, this study aims to identify opinion leaders within the realm of SNS, their influence toward the electoral progress, and determines if SNS are an effective medium for the generation, replication, and dissemination of political messages.
