CSPI is another group in the same vein as People for the American Way. They push a liberal, nannyist agenda behind a masthead that makes you think they're actually DOING something that would be rational and make actual sense to be involved in.
In actuality, if a rational, thinking person examines their data, it does not stand up to logic. Warping the scientific method to achieve an end isn't what it's all about.
