There is a disconnect between the popular understanding of the role of money in American politics and the lessons from social science research. The foundational research in this field finds that campaign spending has at best negligible impacts on election outcomes. Similarly, decades of research reveal very little evidence that campaign contributions or even lobbying has significant effects on the content of public policy. These findings are corroborated by cutting edge research on the effects of campaign finance reforms both at the federal level and in the states.
