Sabbia Gale-Donnelly told ABC News that she thought Clinton represented "someone for me and my friends to look up to because she never quits."
She said that she admired Clinton, and believed that she stood up for women as a politician, and said that her candidacy proved that women "can do everything."
"I think she's devoted her entire life to making things better for women," Sabbia said of Clinton.
She made a sign for the event based on the children's book "The Little Engine That Could" that said "'I think I can, I think I can, I think I can, I know I can, I know I can' -- because she can," Sabbia said.
She said that she didn't know whether she wanted to follow in Clinton's footsteps and enter politics, but her current interest could align with the historic occasion of Clinton being the first woman to be nominated for president by a major political party.
"Right now, I really want to be a history teacher," Sabbia said.
