The press is filled with sad stories about venerable for-profit newspapers that have been forced to declare bankruptcy and shut down. So it’s striking that the billionaire liberals Herb and Marion Sandler have decided now is the time to fund a new nonprofit group called ProPublica whose mission is to serve the public interest by funding independent investigative journalism. Too bad Pro Publica churns out little more than left-wing hit pieces about Sarah Palin and blames the U.S. government for giving out too little foreign aid.
