"She is incredibly busy," a current Clinton aide said. "She's doing a lot with the foundation, she's doing a lot with the Clinton Global Initiative. She's doing a lot of (teaching at) NYU. She's really busy, but I do think you can start to see there's a common thread to everything she's doing."
"She was great to work with," said Brian Ellner who worked with Chelsea Clinton on the same sex marriage issue in New York. "She is enormously enthusiastic and supportive on the issue, but in addition, she wanted to do real work. As opposed to just making appearances, she actually came in a couple of times and did phone banking, making calls all around the state urging New Yorkers to support marriage equality and to call their state representatives."
Ellner said the younger Clinton "is enormously popular and has really come to represent her generation of young Americans who feel strongly on this issue and many others."
"Whether it is pursuing elected politics or increasing her role at the foundation or doing other things because she is right on all of the issues, she's working extraordinarily hard to help people," Ellner said. "I think she really represents her generation extraordinarily well."
During her mother's 2008 presidential campaign, Chelsea Clinton campaigned throughout the country stumping on her mother's behalf.
It was one of her first public roles and although she didn't answer press questions at the events she got the experience of wooing crowds, as well as taking questions in town halls, not the easiest thing for even the most seasoned politicians to do.
The 2008 Clinton staffer said Chelsea Clinton became an "active member" of the campaign, something she would likely repeat if her mother decides to run in 2016.
"It gave her a taste of what it means to be a public figure in the more traditional sense," the former aide said.
Not everyone is convinced she is bound to run for office.
"It's not a given that she will have a public life in elected politics," the former staffer said. "I would tell you, I don't think she's going to. I think she would end up being a reluctant candidate at this point in time."
