Data & Methods: Leveraging a large-scale dataset gathered through targeted Facebook advertisements across multiple election cycles in the United States. The analysis employs quantitative methods including regression models and comparative assessments of survey responses.

Ideological alignment with candidates appears to vary substantially depending on geographic context within states. Additionally, social media platforms like Facebook capture these preferences effectively.
