IF YOU EVER want a window into the needs and desires of the labor movement, you should listen to Stewart Acuff. And if you get within 50 yards of Acuff, you'll be listening: The snow-bearded activist, now the AFL-CIO's director of organizing, projects his voice like an opera singer. He grips the podium, white-knuckled. He clasps his hands, then pulls them apart with a snap. When I saw him at the Take Back America conference in Washington in March, his reedy voice grew rougher and louder as his speech went on. "My brothers and sisters," he said, "if we go into 2008 with an even larger mobilization of workers behind this legislation, with even more commitment to win the election in 2008, and put this on the agenda in 2009, I'm here to tell you today that we will pass this legislation, in the House, overwhelmingly! We will pass it in the Senate! We will defeat a Republican filibuster! And we will have a president who signs the Employee Free Choice Act! And we can get back to the business of restoring the American dream for millions and millions of workers!"
