Abstract

This thesis examines how social media shapes voter perceptions of candidate ideology and economic issues, and how these perceptions influence electoral decision-making. As digital platforms increasingly serve as primary sources of political information, exposure to negative content and patterns such as doom-scrolling can affect voters’ understanding of political realities. The study explores how social media reinforces preexisting beliefs, amplifies stereotypes, and creates echo chambers that shape both perceptions and choices in elections. Using survey data on US senators collected during the 2016, 2018, 2020, and 2022 election cycles, the research investigates the mechanisms by which digital media influence voter behavior. It also considers moderating factors, such as age, education, and demographics, that shape how individuals interpret and respond to online political content. The findings aim to provide insights into the intersection of technology, information processing, and electoral behavior, highlighting the broader implications of digital media on democratic participation. By illuminating how social media can subtly influence voter cognition and decision-making, this research deepens understanding of political communication in the digital age. It informs strategies to promote informed and equitable civic engagement.
