It's not the first time Chelsea Clinton has dissed her dad to promote her mom's candidacy. During a campaign stop in North Carolina, Chelsea said her mother would be a better president than her father "because she is more prepared and more progressive."
Clinton told about 300 people at Duke University on Tuesday that former President Bill Clinton didn't have a complete grasp of the inner workings of Congress when he took office in 1993.
The former first daughter said her mother, Democratic presidential candidate Hillary Rodham Clinton, will benefit from her time as a New York senator.
Only last month, Chelsea Clinton was videotaped telling a crowd in Pennsylvania that "I do think she'll be a better president" than my father.
