American politics has become sharply polarized. Partisan deadlock has prevented the addressing of critical public policy issues. A prime example is Congress’s inability to pass campaign finance legislation. Corporations spend unlimited amounts of company funds to promote management’s preferred candidates without disclosure. The distortive effects of large unaccountable corporate political expenditures are evident, and the opportunity for corrupting our politics is clear. In addition, large undisclosed corporate contributions pose a threat to a well-functioning marketplace and democracy. This chapter addresses the challenge of addressing corporate political spending through the informal, non-state suasion and advocacy of the nonprofit Center for Political Accountability. CPA is a case study in successful private ordering, prompting S&P 500 companies to disclose corporate political spending; develop policies that will ensure good compliance and governance; adopt codes of conduct to reflect and inspire pro-accountability behavior; and successfully compete with other firms for best disclosure and accountability practices.
