Democratic senators sign secret letter backing Hillary in 2016.

Female Democratic senators sign a 2016 Hillary letter encouraging her to run for president.

AT AN event hosted by Emily’s List, Democratic female senators unveiled a secret. They’ve reached out to in a secret Hillary letter to urge her to run for president in 2016, with Senator Elizabeth Warren joining.

This is what’s needed, a continual push and public campaign so that Hillary has no doubt that she’s needed and simply can’t say no. Mind you, I have never thought she would say no.

Reporting from ABC News [h/t Capital New York]:

All of the female Democratic senators signed a secret letter to Hillary Rodham Clinton early this year encouraging her to run for president in 2016 ““ a letter that includes the signature of Sen. Elizabeth Warren and other senators who are mentioned as potential candidates, two high-ranking Democratic Senate aides told ABC News.

The letter, organized at the urging of Sen. Barbara Boxer, D-Calif., was meant to be a private show of support from a group of 16 high-profile former colleagues and fans who are now senators, urging Clinton to do what much of the Democratic Party assumes she will, the aides said.

The existence of the letter was not revealed publicly until this week, when Sen. Kay Hagan, D-N.C., mentioned it at an event in New York City on Monday. That was an apparent slip-up that prompted a round of apologetic e-mails from her Senate office to other offices on Capitol Hill, according to the aides.

“All of the Senate Democratic women have written her a letter encouraging her to run,” Hagan told a gathering organized by EMILY’s List, according to Capital New York. The event was part of the group’s “Madam President” series, which is organizing events around the country to promote interest in a female Democratic presidential candidate.
