The Working Families Party, which Sen. Bernie Sanders (I-VT) called “the closest thing” to “my vision of democratic socialism” when he got the group’s endorsement in 2016, is backing a different horse the time around: Sen. Elizabeth Warren (D-MA).

According to the New York Times, the party made its endorsement on Monday after members voted, with Warren grabbing more than 60 percent of the vote.

“If our focus is on victory, we can’t be delusional about it,” Maurice Mitchell, Working Families Party’s national director, told the Times. “You don’t defeat the moderate wing of Democrats through thought pieces or pithy tweets, you defeat their politics through organizing.”

The Sanders campaign touted the unofficial support of working families in a statement.

“The Bernie Sanders campaign is built from the support of millions of working people across the country, with our leading donors being Walmart workers, teachers and nurses,” deputy communications director Sarah Ford told TPM. “We look forward to working with the Working Families Party and other allies to defeat Donald Trump. Together, we’ll build a movement across the country to transform our economy to finally work for the working class of this country.”
