Watch out! ACORN is back -- in all but its name. Backed by hundreds of thousands of dollars in union donations, New York Communities for Change -- a rebranded version of the controversial organization that closed up shop amid several scandals -- is acting again as labor's attack dog on controversial issues. NYCC took over ACORN's office on Nevins Street in Brooklyn, shares some of the same board members and uses its membership lists and other resources. (Snip) But when NYCC has to choose between low-income consumers and unions, it dances to Big Labor's tune.
