Though Massachusetts Senator Elizabeth Warren has not endorsed 2016 Democratic front-runner Hillary Clinton in the Democratic Primary — or her rival, Vermont Sen. Bernie Sanders — it's not too late for Warren to earn the Vice President slot on a Clinton ticket, according to the New York Times.

Clinton advisers are in talks about prospective running mates and will begin vetting a list of 15 to 20 options by late spring, the Times reported. While the campaign did not name Warren specifically, they did say that Clinton would consider a woman as her running mate. Warren, who is quite popular among Sanders supporters — 33 percent of whom have said they would not vote for Clinton — would be a strategically wise choice.

An all-female ticket would mean an even greater sense of history to Clinton's presidential bid.

Clinton already has a strong platform on women's issues, and has stressed her support of Planned Parenthood, as well as the historical significance of having a woman in office, throughout her campaign.

Choosing Warren as a running-mate would further reinforce the significance of Clinton's run to female voters and could bring progressive Democrats who would otherwise not vote for Clinton into the fold — though Warren has declined to endorse the former Secretary of State up to this point.

Warren could sway Bernie voters toward Hillary.

Sanders and his supporters have been particularly critical of Clinton's relationship with Wall Street, and repeatedly pointed out that she has taken large speaking fees from Goldman Sachs and other major financial players. Warren shares many of Sanders views on corporate greed and the financial sector, and stood up to defend Sanders against attacks from Goldman Sachs CEO Lloyd Blankfein in February.

Warren has also been a major advocate for reforming student loans, an important issue among Sanders supporters, many of whom are millennials.

Warren also has a large base of grass roots support that could benefit Clinton greatly. "Warren is a prodigious online fund-raiser who could help Clinton attract the tens of millions of grass-roots donations that have filled Sanders’ treasury," the Boston Globe reported. "She raised $45 million for her 2012 Senate race, with 47 percent of the funds coming from small donors, according to the Center for Responsive Politics, which tracks political spending."

If Clinton and Warren decide to run together, it's possible that lukewarm Bernie supporters would switch over to the all-female ticket instead of backing the Vermont Senator.

Clinton is still keeping her options open.

It's worth noting that while the Clinton team has not named Warren, the candidate, her husband, and campaign advisers have mentioned other possible picks for Vice President.

The Times reported:

"Among the names under discussion by Mrs. Clinton, Mr. Clinton and campaign advisers: Senators Tim Kaine and Mark Warner, former governors from the key state of Virginia; Senator Sherrod Brown of Ohio, who represents both a more liberal wing of the party and a swing state; former Gov. Deval Patrick of Massachusetts, a prominent African-American Democrat; and Thomas E. Perez, President Obama’s labor secretary and a Hispanic civil rights lawyer."

Nonetheless, anonymous campaign advisers told the Times that Warren had not been ruled out, and a Clinton-Warren ticket might have major pay-off for the Democratic front-runner.

“Real folks are pushing Warren. I’m into it,” one member of Clinton’s inner circle said, according to Huffington Post Washington bureau chief Ryan Grim.
