I did mention Halperin's Soros connection in the article. Please see the second para:
"Halperin remains active politically, serving as a senior fellow at the 'Center for American Progress.' As detailed by the invaluable Discoverthenetworks, CAP is a George Soros-funded organization founded on the risible principle that American colleges and universities are dominated by . . . conservatives, and that it is 'time for progressive students to start winning the battle of ideas.'"
