This book is intended to respond to Congress's ongoing interest in campaign finance policy following the Supreme Court's April 2014 McCutcheon decision. The book relies on a question-and-answer format designed to highlight key information in a brief and accessible way. This book offers a preliminary analysis of major policy issues and potential implications that appear to be most relevant as the House and Senate assess the ruling and consider how to respond. The book discusses possible implications of the case for campaign fundraising or disclosure to illustrate policy issues that might be relevant for congressional consideration. This book also includes updated material that emphasises the issues most prominently before the 113th Congress. It also discusses foundational information about major elements of campaign finance policy.
