This document summarizes Laura Lueninghoener's dissertation on authenticity in the online campaigns of Barack Obama in 2008 and Bernie Sanders. It focuses on how Obama successfully engaged young voters through an interactive social media strategy, mobilizing over 23 million youth voters. Obama cultivated authenticity through various social media platforms like Facebook, Twitter, YouTube, and blogs to connect directly with voters and share his message and values. His grassroots campaign, email strategy, and central website MyBarackObama.com helped people get involved through organizing, fundraising, and volunteering. This case study establishes Obama's campaign as pioneering in its innovative and engaging use of social media.
