This research uses the 2010-post election survey by Pew Internet and American Life project and traces the direct and indirect paths of online political information use, Facebook political information use, and mobile phones political information use to political participation to online and offline political participation. Indirect paths are traced through the paths of wider view exposure and the credibility to online and offline political participation. The theoretical framework of the O-S-O-R model is used to guide the path analyses for this research. This research finds that both online political information use and Facebook political information use expose respondents to a wider diversity of views, but that it does not lead to political participation. Furthermore, all three mediums are found to be credible sources of information leading to online political participation with different strengths, while Facebook political information use also leads to offline political participation. Thus, credibility is an important factor and even suggests the possible need for an opinion leader. This is especially so for the use of Facebook, which has the best balanced information dissemination structure its friend network of identifiable people, organisations, and institutions. Facebook also provides the best platform for critical debate and engaging potential voters. Mobile phone political use is also supportive of political participation, but is more questioned in terms of whether the participation it brings is able to lead to critical debate.
