The Secret Money Project
The Secret Money Project, a joint endeavor by the Center for Investigative Reporting and NPR, tracks the influence of hidden money from independent groups funding advertising campaigns during the 2008 elections. Changes in campaign finance laws and political strategies have ratcheted up the influence of such groups in the current election cycle, as these groups are not limited in how much money they can raise and often aren't scrutinized like the candidates or party committees. An interactive map identifies the groups behind the smear campaigns by state.
