The impact of social media in political campaigning around the world is undeniable. Latest statistics show that close to three fourth of U.S. adults use social networking sites such as Facebook and Twitter, with social network use becoming almost ubiquitous among young adults, according to recent data from the Pew Research Center (2018). Globally, an estimated 2.62 billion people use social networks on a daily basis in 2018, with that number projected to reach 2.77 billion by 2019 (Statista, 2018). With their tremendous growth, social media have become an indispensable part of modern political campaigning, both in the United States and internationally. Platforms such as Facebook, Twitter, or Reddit have changed how political campaigns are run; how politicians and the public access and share political information; and the way we learn about politics, form opinions and attitudes, and ultimately engage in or disengage from the political process. While social media have clearly affected our understanding of political communication and its effects on the public, it is difficult to see clear monolithic effects. A 2009 meta-analysis showed that Internet use in general had positive, although relatively small, effects on different aspects of political engagement (Boulianne, 2009). Similarly, a 2015 meta-analysis demonstrated only limited effects of digital media use on political participation, showing that only half of 170 reported effects from 36 selected studies were statistically significant (Boulianne, 2015). Yet another meta-analysis found generally positive effects of social media on three different dimensions of engagement, namely, social capital, civic engagement, and political participation, when surveying 116 relationships/effects reported in 22 different studies (Skoric, Zhu, Goh, & Pang, 2016). These comprehensive aggregate studies offer evidence that the effects of social media consumption and use are hardly uniform across different contexts and groups. For example, studies with random samples of youth are more likely to identify a significant effect, compared with general population samples (Boulianne, 2015). Also, studies that rely on panel data are twice less likely to find positive and statistically significant relationships between social media use and political participation (Boulianne, 2015). Studies have also noted that the relationship between Internet use and political engagement varies depending on type of use. For example, findings by Gil de Zuniga, Bachmann, Hsu, and Brundidge (2013) suggest that only expressive 770437J MQXXX10.
