NORMAN SOLOMON – Like other Bernie Sanders delegates in Philadelphia a few weeks ago, I kept hearing about the crucial need to close ranks behind Hillary Clinton. â€œUnityâ€ was the watchword. But Clinton has reaffirmed her unity with corporate America. Rhetoric aside, Clinton is showing her solidarity with the nemesis of the Sanders campaign — Wall Street. The trend continued last week with the announcement that Clinton has tapped former senator and Interior secretary Ken Salazar to chair her transition team.
