In a sign that a loud portion of the Democratic Party’s liberal wing is still uninspired by a potential Hillary Clinton candidacy, the Working Families Party of New York is adding its name to the list of backers urging Sen. Elizabeth Warren (D-Massachusetts) to run for president.

The Working Families Party joins two other liberal groups, Democracy for America and, in trying to inspire Warren to challenge Clinton. The party’s entry is undoubtedly a message to Clinton, who served parts of two terms as a senator from New York.

“Senator Warren is the nation's most powerful voice for working families fighting against a set of rules written by and for Wall Street,” New York Working Families Party Director Bill Lipton said in a statement. “That's the debate we want to see, and that's why we're urging Senator Warren to run for President."

The Working Families Party, which is financed by some of New York City’s largest unions, had supported both of Clinton’s Senate runs. It’s a coalition of labor unions and progressive groups and activists.


Warren, meanwhile, a darling of the progressive left, has repeatedly insisted that she’s not running for president, even going so far recently as to clarify her position in multiple tenses.

Undeterred, the “Run Warren Run” campaign has begun setting up offices in both Iowa and New Hampshire. They have claimed more than 300,000 signatures on a petition urging Warren to run. Last week, the campaign announced the hiring of a New Hampshire state director.


“Adding the voices of New York Working Families Party members to the campaign continues to build momentum behind the effort to encourage Senator Warren to enter the 2016 race for president, and we couldn't be happier to have their grassroots talent and support on the team,” said Charles Chamberlain, the executive director of Democracy for America.

Although polls have shown Warren gaining traction as the firm No. 2 choice behind Clinton, she’s still well behind. Overall, Clinton still getting more than 50 percent of Democratic support in both state-level and national polls.


And a key group with which she struggled during her last presidential run in 2008 — young people — is showing signs of rallying behind her potential candidacy. Fusion’s Massive Millennial Poll, which surveyed 1000 people aged 18-34 about everything from politics to dating to race issues, found 38 percent of the millennials surveyed — including 57 percent of millennial Democrats surveyed in the poll — said they would support Clinton for president.
