No organization likes bad publicity. And when allied organizations create it, disavowing ties to them becomes attractive. The Service Employees International Union (SEIU) has exercised that option - at least on the surface. On Wednesday, September 30, the union's secretary-treasurer, Anna Burger, told a congressional panel that her organization no longer has a working relationship with the New Orleans-based nationwide nonprofit "anti-poverty" network ACORN, an acronym for the Association of Community Organizations for Reform Now. ACORN, as almost everyone in this country with a pulse knows by now, has been the target of federal and state investigations into a wide range of criminal activity. A very embarrassing and widely-aired homemade undercover video hasn't helped its case. Yet all the same, the union's move looks like a case of bait and switch.
