Politico discovers yet another Koch Brothers ultra right-wing political slush fund

Politico says the Arlington, Va.-based group, called "Freedom Partners," was unknown to nearly everyone in politics; it "raised and spent $250 million in 2012 to shape political and policy debate nationwide," cutting checks as large as $63,000,000 to conservative advocacy groups:

The group has about 200 donors, each paying at least $100,000 in annual dues. It raised $256 million in the year after its creation in November 2011, the document shows. And it made grants of $236 million — meaning a totally unknown group was the largest sugar daddy for conservative groups in the last election, second in total spending only to Karl Rove’s American Crossroads and Crossroads GPS, which together spent about $300 million.
