<human>:  Why did Howard Dean resign?
<bot>: Well, he was found out to have a sexual relationship with a young staffer. The young woman was 19 years old at the time, and she was a volunteer for the campaign. Dean was not married at the time, so he was breaking the law. Dean had been in the news before for his relationship with a woman in his office, and the campaign staffer was a volunteer. This is not a good look for the Democratic party.
