Chelsea Clinton said she was not aware of the extent of sexism in the United States until her mother's campaign.

Speaking at the Young Democrats convention in the Research Triangle Park today, the former first daughter said she has been surprised by the things people have told her on the campaign trail about her candidacy.

"I really didn't get how much sexism there was in this country until I was at a rally in New Hampshire and someone came up to me and said 'I just can't see a woman being commander in chief,'" she said.

She said another woman told her that Hillary Clinton was "a little too smart."

"It makes me uncomfortable," she said the woman told her.

At another rally that she did not attend, she noted that two young men said, "with all seriousness, 'Iron my shirt.'" (Read more here about the incident.)

She said she was also disturbed that some people think it's funny that there is a nutcracker of her mother in a "not respectful posture."
