The powerful Culinary Workers Union Local 226 announced on Thursday that it would not be endorsing a Democratic presidential candidate ahead of the Nevada caucuses on Feb. 22.

“We are going to endorse our goals ― what we’re doing, that’s what we’re going to endorse,” the union’s secretary-treasurer Geoconda Argüello-Kline said at a press conference in Las Vegas on Thursday afternoon. “We’re not going to endorse a political candidate.”

The union’s three top policy goals are making sure that “one job is enough” for every worker to afford their livelihood; protection of the union’s “choices” to maintain its own health care plan; and immigration reform that provides a pathway to citizenship for an estimated 11 million undocumented immigrants living in the United States.

The nonendorsement is sure to be a source of relief for Sens. Bernie Sanders (I-Vt.) and Elizabeth Warren (D-Mass.), whose support for “Medicare for All” is at odds with the union. The union said the bilingual candidate scorecard it distributed to members, which is critical of Sanders and Warren’s Medicare for All plans, is as close to an endorsement as the union will provide.

It is also likely a disappointment to former Vice President Joe Biden, who would be a natural choice for a union heavily composed of the working-class voters of color who form Biden’s base.

In what was perhaps an implicit acknowledgment of the unique relationship with Biden, he was the only candidate Argüello-Kline mentioned by name during her prepared remarks.

“We respect every single candidate right now. We know they are great people,” she said. “We know Vice President Biden for many years. We know he’s been our friend.”

Biden is due to visit the union’s Culinary Training Academy in North Las Vegas on Saturday. But Argüello-Kline and union spokeswoman Bethany Khan denied on Thursday that the appearance reflected any kind of partiality to Biden, noting that any of the Democratic candidates is free to visit the academy.

The union has held seven town halls for its members to hear from presidential candidates. Sanders addressed the union’s members on Dec. 10.

In addition, the nonendorsement creates an opening for other moderate contenders with whom the union is more aligned on health care policy. Former South Bend, Indiana, Mayor Pete Buttigieg and Sen. Amy Klobuchar (D-Minn.) won second and third places in the New Hampshire primary on Tuesday, potentially setting the stage to replace Biden as the moderate alternative to Sanders.

The endorsement of Culinary Union, which counts among its members 60,000 casino and hotel workers across Nevada, is highly coveted by Democratic presidential candidates. The union boasts a legendary turnout operation that helped hand the state’s caucuses to Hillary Clinton in 2016 and kept the state in the Democratic column in the general election, even as many traditional party strongholds fell to Donald Trump.

The Culinary Union’s endorsement announcement follows two days of tensions between the union and Sanders’ campaign revolving around the union’s objection to his Medicare for All plan. The union is one of several labor groups opposed to Medicare for All because it would mean forgoing private plans they have fought years to win in favor of an expanded public coverage program.
