The DLC's mission was to define the Third Way. I did some research on this a few years back, and Obamas name did come up: http://nord.twu.net/acl/thirdway.html
From the New York Observer, March 4, 2008:
"Mr. From said Mr. Obama had an intellectual, and not just tactical, connection to the D.L.C.
“I mean his chief economist, Austan Goolsbee, is a fellow at the Progressive Policy Institute, which is our think tank,” he said."
It looked like Obama "left" the DLC in March 2005, at least that's what I quoted at the ACL. I'm not sure if using a DLC boy as his chief economist qualifies him to claim he left the DLC. I guess what this really means is we can't expect a revival of our economy based on the American System of Political Economy, besides, the PPI is only one of hundreds of think tanks that promote communitarian economics; the American system is outdated and a dangerous influence on Third World nations. Nobody who's anybody would ever be so uncouth as to bring it up in mixed company.
Here's a Rep Major Owens explaining in Jan 2008 why Hillary must rescue herself from the DLC. He gives a little background on it for us: http://www.huffingtonpost.com/rep-major-r-owens/hillary-must-rescue-herse_b_81827.html
