Before joining the campaign trail with her mother in January, Chelsea Clinton said she had no idea how much sexism still existed in the nation.

“Two guys in New Hampshire stood up and shouted ‘Iron my shirt,’ ” Chelsea Clinton said. “They were serious. I was shocked that they were serious. But I was even more shocked to see that no one seemed the think that it was a news story. It wasn’t something you saw a news clip of.”

Even today, Chelsea Clinton meets people, often women, who say her mother is the best and smartest candidate, but that they “are not comfortable with a woman as commander in chief,” she said.

Chelsea Clinton’s university tour brought her to University Park to convince voters that her mother, Sen. Hillary Clinton, D-N.Y., is the best candidate for the Democratic nomination.

“This is where my grandfather and uncle graduated from,” Clinton said, adding that her grandfather played football for the Nittany Lions in the 1930s. “I watched many games with him before he died.”
