The other major sponsor of the Tea Party movement is Dick Armey’s FreedomWorks, which, like Americans for Prosperity, is promoting events in Washington this weekend. Under its original name, Citizens for a Sound Economy, FreedomWorks received $12 million of its own from Koch family foundations. Using tax records, Mayer found that Koch-controlled foundations gave out $196 million from 1998 to 2008, much of it to conservative causes and institutions. That figure doesn’t include $50 million in Koch Industries lobbying and $4.8 million in campaign contributions by its political action committee, putting it first among energy company peers like Exxon Mobil and Chevron. Since tax law permits anonymous personal donations to nonprofit political groups, these figures may understate the case. The Kochs surely match the in-kind donations the Tea Party receives in free promotion 24/7 from Murdoch’s Fox News, where both Beck and Palin are on the payroll.
