Terrific new draft paper with some key data from Abhey Aneja, Jacob Grumbach, and Abby Wood. Here is the abstract:

Our deregulated campaign finance system has a race problem. We use innovations in statistical methods and the universe of campaign contributions for federal elections to analyze the racial distribution of money in American politics between 1980 and 2012. We find that white people are severely overrepresented among donors. A stunning 91% of money contributed to state and federal candidates by individuals has come from non-Hispanic white donors. The racial gap in campaign contributions is significantly greater than the gap in voter participation and elected office holding. It is also relatively constant across time and elected offices.

This result is an important missing piece in the conversation about equity in political participation. We argue that the courts and Congress should take steps to address the racial gaps in campaign finance participation. The participation and representation problems that flow from racial inequality in deregulated campaign finance could inform claims under the Voting Rights Act (VRA), and politico-financial inequalities certainly bear on the normative problems that the statute intends to address. But the most politically viable way to address the campaign finance racial gap lies in adoption of public financing for political campaigns, which offer the promise of increasing the racial representativeness of campaign contributions. When racial representativeness in contributions is improved, improved equality in the distribution of resources and power in electoral and political systems should follow.
