From a report on Politico today:
An Arlington, Va.-based conservative group whose existence until now was unknown to almost everyone in politics raised and spent $250 million in 2012 to shape political and policy debate nationwide.
The group, Freedom Partners, and its president, Marc Short, serve as an outlet for the ideas and funds of the mysterious Koch brothers, cutting checks as large as $63 million to groups promoting conservative causes, according to an IRS document to be filed shortly.
Five U.S. Supreme Court justices -- all Catholics -- gave us Citizens United, which opened up these floodgates to Big Money.
