Aug. 28, 2012–MapLight has run an analysis of independent expenditures made from Jan. 1, 2011 to July 31, 2012 by so-called super PACs to influence congressional and presidential races in the 2012 election cycle.
In July 2012, super PACs that file monthly reports spent $29.6 million on independent expenditures across the country. Of that total, $25.9 million (88 percent) was spent by just five super PACs. Figures from super PACs that file quarterly reports will not be available until October.
