The emergence of social media has changed the way in which political communication takes place in the United States. Political institutions such as politicians, political parties, foundations, institutions, and political think tanks are all using social media, Facebook and Twitter, as a new way of communicating with and engaging voters. Regular individuals, politicians, "pundits" and thought leaders alike are able to voice their opinions, engage with a wide network, and connect with other likeminded individuals. The active participation of social media users has been an increasingly important element in political communication, especially during political elections in the 2000s.
