Ready for Warren is no longer exclusively ready for Warren. The organization is keeping its efforts to draft Elizabeth Warren in place, but for those supporters who are giving up and want to shift gears and back another candidate, they have launched a project backing Sen. Bernie Sanders' presidential bid.

In an email to supporters, the group's organizers said they were launching an initiative called Ready to Fight, and that when members were asked about 2016, 56 percent supported Sanders, leading the organization to give the Vermont Democrat its support.

An op-ed for CNN by Ready for Warren campaign manager Erica Sagrans and cofounder Charles Lenchner explained the decision to back Sanders.

"Sanders has captured the imagination and support of people looking for a real progressive challenger in the 2016 Democratic primary," they wrote.

But in an email to supporters, Ready for Warren insisted that the movement to draft Warren effort was not over yet.

"Ready for Warren will continue to be a place for everyone who wants to organize to make the case to Warren, and the country, that she should run," the email said.

By hosting these two organizations, Ready for Warren likely is trying to settle the predicament of how to keep momentum for their draft effort while maintaining the energy of people in the tent who are ready to channel their efforts toward an actual candidate's campaign.

Warren has repeatedly rebuffed pushes to jump in the race from Ready for Warren and Run Warren Run, which suspended its efforts last week and instead said it would focus on helping Warren in her fight for progressive causes.

The boosters who held onto a potential Warren candidacy for so long, though, aren't all just going to bounce to Bernie Sanders. Saba Hafeez, who helped drop off signatures to Warren's office to ask her to run for president, and was a campus organizer at the University of Iowa for the effort, said last week that she had seen former Maryland Gov. Martin O'Malley speak in Iowa City and was planning on seeing Hillary Clinton speak in Sioux City.

"I haven't decided what I'm doing next, but I would love to work in another campaign," Hafeez said.

Warren supporters are trying to show the campaigns that they are a valuable constituency in the Democratic Party, but it is unclear how much of an influence or help that Warren's backers would be to Sanders, or if their movement to him would have any effect on Clinton's front-runner campaign.
