Zogby International conducted interviews of 703 union members chosen at random from a Zogby database of self-identified union households nationwide. All calls were made from Zogby International headquarters in Utica, N.Y., from June 25 through June 28, 2004. The margin of error is ± 3.8 percentage points. Slight weights were applied to age, race and gender to more accurately reflect the sample population.
