MapLight has conducted an analysis of independent expenditures made by super PACs across the country from Jan. 1, 2011 through June 30, 2012 and found that almost $138 million has been funneled by big-monied interests to dictate outcomes of the 2012 election.

Super PACs have already made over $30 million in independent expenditures to influence House and Senate races in the 2012 election cycle, in addition to the nearly $107 million spent swaying the outcome of the race for the White House.
