What’s more, Wal-Mart gives a large sum from its corporate coffers to liberal advocacy groups, the Capital Research Center concluded in an August 2006 review of IRS records. The study by researcher David Hogberg, now a senior analyst at the National Center for Public Policy Research, found that of the $150 million in donations given by Wal-Mart in 2004, only $2,530 went to politically right-of-center organizations while 289 times as much went to left-of-center think tanks, a total of $732,350.
