This document discusses how social media has changed and will continue to impact political campaigns and elections in the United States. It explores how politicians now use social media to directly engage with voters, especially younger generations, and how advocacy groups are also utilizing social media to encourage civic engagement. By 2016, social media use had become a common campaign tool as demonstrated by Barack Obama's successful use of sites like Twitter and Facebook in his presidential elections. Future research questions consider whether social media changes how people think about elections and whether following politicians on social media makes people more likely to vote.
