Bush daughter hopes Hillary Clinton runs in 2016

George W. Bush's daughter Barbara Bush does not know whether she'll end up casting a presidential ballot for Hillary Clinton in 2016, but she sure hopes she has the option.

In an upcoming interview with People, due to hit newsstands on August 26, Bush said she hopes Clinton makes another bid for the White House, calling the former secretary of state "unbelievably accomplished."

Still, Bush clarified that her 2016 vote remains up for grabs: "I don't know who she'd be running against."

Despite her Republican heritage, Bush has cultivated a streak of political independence: In 2011, she voiced her support for same-sex marriage, and in 2010, she told Fox News that she is "glad" President Obama was able to muscle a healthcare reform bill through Congress.

The interview with People focused primarily on Bush's work with Global Health Corps, a nonprofit group she helped launch in 2008 that recruits young professionals from a variety of fields to work on difficult global health issues like infant mortality and HIV/AIDS.

Former Florida Gov. Jeb Bush, Barbara Bush's uncle, is considered a potential Republican candidate for the presidency in 2016.

Bush's encouragement of Hillary Clinton marks the latest bout of public rumination from the Bush family about the prospective 2016 presidential field. In April, her grandmother, former first lady Barbara Bush, told NBC that she does not want to see Jeb Bush throw his hat into the ring.

"He's by far the best qualified man, but no," the elder Barbara Bush said when asked if she'd like to see Jeb run. "I really don't. I think it's a great country, there are a lot of great families, and it's not just four families or whatever. There are other people out there that are very qualified."

"We've had enough Bushes," she said.

But former President George W. Bush offered nothing but encouragement for his younger brother's potential bid. "He would be great," he told ABC. "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!"

Former first lady Laura Bush agreed with her husband. "I'd love to see Jeb run," she told CBS This Morning, saying a match-up between Jeb Bush and Hillary Clinton would be "interesting."

In a separate interview published Thursday, first lady Michelle Obama told Parade magazine that she believes America is ready to elect a female president. "Yes, I think the country is ready for it," she said. "It's just a question of who's the best person out there."
