Investigative Journalism

ProPublica "is an independent, non-profit newsroom that produces investigative journalism in the public interest... by producing journalism that shines a light on exploitation of the weak by the strong and on the failures of those with power to vindicate the trust placed in them."  The effort led by this group to make public (called "Free the Files") the amount of behind-the-scenes lobbying money that is spent by non-profit groups (called super-PAC's) on TV advertisements to prop up their candidates, is entirely voluntary. You may be surprised with some of the findings (25% of the files reveal an astounding $264m in TV ad spending, with the Obama camp buying the biggest share so far!)
