The Wesleyan Media Project tracks and analyzes all broadcast advertisements aired by or on behalf of federal and state election candidates in every media market in the country. Since the 2010 election cycle, we have been providing real-time information on ad spending in federal election campaigns across the country, who specifically is doing that spending and which candidates are benefiting. The Project is a collaboration among Professors Erika Franklin Fowler (Wesleyan University), Michael M. Franz (Bowdoin College) and Travis N. Ridout (Washington State University). Our work would not be possible without our amazing team of undergraduate Research Assistants. We also thank Ken Goldstein, Sunlight Foundation, Knight Foundation, Rockefeller Brothers Fund, MacArthur Foundation and our respective institutions, including Wesleyan’s Quantitative Analysis Center, for their support in previous election cycles.
