For many years Martha Stewart was a popular expert in home decorating, an arbiter of good taste, and a very successful businesswoman. In June 2002 she first came under attack amidst rumors of insider stock trading. At that time, a series of Gallup polls each contacted over 1000 people to ask about their overall opinion of her. Those polled could answer favorable, unfavorable, or that they did not know who she was. Results are summarized in the table on the following page.
