Actor Mark Ruffalo is lending his star power to the effort to draft Elizabeth Warren into the 2016 presidential race, co-hosting a party with pro-Warren groups in New York City Thursday night that will also feature other liberal creative types and activists. The Artists for Warren party, to be held at the Manhattan loft of Julie Pacino (Al Pacino’s daughter) and screenwriterJennifer DeLia, will feature food and drinks from chef/indie rocker Brooks Headley and music by Tennessee Thomas. “Attendance is not an endorsement of Warren for President,” reads an invitation obtained by msnbc. “Rather, this is an invitation to meet as a group of artists and activists to discuss how an Elizabeth Warren run could change the conversation, build progressive power, and move us closer to our shared vision of an America where everyone has a fighting chance.” Run Warren Run, the draft campaign started by MoveOn.org and Democracy for America, are hosting the event, along with the super PAC Ready for Warren. Officials from the groups will be on hand, along with Eli Pariser, the former MoveOn official who went on to found Upworthy.
