Add former President George W. Bush's daughter Barbara Bush to a growing list of people who want to see Hillary Clinton run for president.

In an interview with People magazine, the daughter of the Republican president said she believes the former first lady and secretary of state is "unbelievably accomplished" and hopes she will run for president in 2016.

But a Clinton candidacy wouldn't necessarily earn young Bush's vote right away.

"I don't know who she'd be running against," Bush, 31, said in the interview, which is due to hit newsstands today.

The eldest of the Bush twins is politically unaffiliated despite being part of a well-known Republican dynasty.

She released a 2011 public service announcement on behalf of New Yorkers for Marriage Equality to voice her support for gay marriage; and has worked with a number of other Democratically rooted initiatives. As CEO of Global Health Corps, a nonprofit that focuses on health equity, Bush has partnered with both the Clinton Health Access Initiative and Michelle Obama's "Let's Move" campaign.

And she suggested that her association with such causes is not grounded in politics.

"We want results," the Texas-born New York City resident said. "We work with people doing great work."

Despite Bush's comments on Clinton, a member of her own family is also the subject 2016 speculation.

Her uncle Jeb Bush, the former Florida governor, and his White House prospects were the center of a family disagreement earlier this year.

"He'd be a marvelous candidate if he chooses to do so. He doesn't need my counsel because he knows what it is, which is 'run,'" brother and former president George W. Bush told ABC News' Diane Sawyer in an exclusive interview.

His comments were at odds with those by the family matriarch, Barbara Bush, who was adamant about keeping the Bush family name out of the White House.

"There are other people out there that are very qualified and we've had enough Bushes," she told NBC's Matt Lauer. "He's by the far the best qualified man, but no."

The full interview with her granddaughter is featured in People magazine's Aug. 26 issue.
