At least two presidents, seven governors and several prominent mayors – from both major parties – have established nonprofits that allow them to raise unlimited, anonymous funds for political spending after election day. In recent years, the risk of dark money in our elections has become apparent, but we pay less attention to the politicking that happens after election day. This report is the first comprehensive analysis of a yawning gap in rules that govern money in politics and government ethics, and poses a serious risk of corruption. It finds that spending by nonprofits that coordinate with elected officials after they take office goes almost entirely unchecked, and calls for new laws to limit political funding by officeholder-controlled nonprofits.
