LEADING THE DAY:

The Nevada caucuses will be held a week from Saturday, and the contest is likely to pose a new set of challenges for the party's presidential contenders.

Sen. Bernie Sanders Bernie SandersKenosha will be a good bellwether in 2020 Biden's fiscal program: What is the likely market impact? McConnell accuses Democrats of sowing division by 'downplaying progress' on election security MORE (I-Vt.) appears to be riding high. On Friday, the Nevada Poll, conducted for the Las Vegas Review-Journal and AARP Nevada, showed the Vermont senator taking the lead in the Battle Born State, followed by former Vice President Joe Biden Joe BidenSenate Republicans face tough decision on replacing Ginsburg What Senate Republicans have said about election-year Supreme Court vacancies Biden says Ginsburg successor should be picked by candidate who wins on Nov. 3 MORE and Sen. Elizabeth Warren Elizabeth WarrenBiden's fiscal program: What is the likely market impact? Warren, Schumer introduce plan for next president to cancel ,000 in student debt The Hill's 12:30 Report - Presented by Facebook - Don't expect a government check anytime soon MORE (D-Mass.). Twenty-five percent are backing Sanders, followed by 18 percent for Biden and 13 percent for Warren.

Nevada is also the first state in the 2020 nominating contest where the vast majority of Democratic voters aren't white. That's likely to boost Sanders's strong support among Latino voters, who make up roughly 20 percent of the Democratic electorate in Nevada.

But Sanders is also facing unexpected trouble with one of the state's most powerful unions, the Nevada Culinary Workers Union, which criticized his plans for Medicare for All. After fierce pushback from Sanders supporters, the union on Thursday said it would decline to endorse a candidate ahead of the caucuses. But the controversy highlighted a rare split between the Sanders campaign and a union base that has been a strong ally. How the controversy impacts the vote remains to be seen.

His low support among black voters has been well documented throughout most of his presidential campaign, but Buttigieg is also struggling to win over Latino voters. A November poll from Telemundo pegged his support among Latinos at just 2 percent. The Nevada Poll released on Friday showed him running neck-and-neck with Sen. Amy Klobuchar Amy KlobucharThe Hill's Morning Report - Sponsored by The Air Line Pilots Association - White House moves closer to Pelosi on virus relief bill EPA delivers win for ethanol industry angered by waivers to refiners It's time for newspapers to stop endorsing presidential candidates MORE (D-Minn.) for fifth place in the state, with each taking 10 percent support.

While Biden is hoping for a top finish in Nevada, his campaign has focused more heavily on South Carolina, the first primary state in which black voters make up a majority of the Democratic electorate. Since launching his campaign last year, he has remained the dominant candidate among those voters. But there are signs that that base of support is beginning to crack. A Quinnipiac University poll released this week showed Biden's support from black voters nationally plummeting to 27 percent, down from 49 percent in a similar poll conducted in January.

At the same time, Biden is facing stiffening competition in South Carolina, most notably from billionaire activist Tom Steyer Tom SteyerTV ads favored Biden 2-1 in past month Inslee calls Biden climate plan 'perfect for the moment' OVERNIGHT ENERGY: Trump administration finalizes plan to open up Alaska wildlife refuge to drilling | California finalizes fuel efficiency deal with five automakers, undercutting Trump | Democrats use vulnerable GOP senators to get rare win on environment MORE, whose heavy spending in the Palmetto State appears to be translating to success in the polls. In two surveys released this month, Steyer jumped into double digits, placing second to Biden in an East Carolina University poll and third in a Post and Courier survey.

To be sure, there are still question marks hanging over the contests in Nevada and South Carolina. But both states are likely to give us a better picture of how the nominating contest is shaping up in more diverse parts of the country.

FROM THE TRAIL:

Warren took direct aim at former New York City Mayor Michael Bloomberg Michael BloombergTop Democratic super PAC launches Florida ad blitz after Bloomberg donation The Hill's 12:30 Report - Presented by Facebook - Latest with the COVID-19 relief bill negotiations The Memo: 2020 is all about winning Florida MORE on Thursday, accusing him of using his multibillion-dollar fortune to buy his way into contention in the Democratic presidential race, The Hill's Julia Manchester reports. Speaking at a town hall event in the Washington, D.C., suburbs, Warren also hammered Bloomberg for his past comments partially blaming the 2008 financial crisis on the end of a practice known as "redlining" in which banks discriminated against racial minorities looking to take out loans to buy homes. "Michael Bloomberg is saying, in effect, that the 2008 financial crash was caused because the banks weren't permitted to discriminate against black and brown people," Warren said. "That crisis would not have been averted if the banks had been able to be bigger racists, and anyone who thinks that should not be the leader of our party."

In comments to The Associated Press, Warren also defended her struggling bid for the Democratic presidential nomination, telling the news outlet that her campaign has raised about $6 million since the Iowa caucuses and that the nominating contest remains "wide open." "There's a lot of froth. It's going to be a long process," she said. The comments came as Warren looks to get back on her feet following two middling performances in the Iowa caucuses and New Hampshire primary. In the caucuses, she placed third after former South Bend, Ind., Mayor Pete Buttigieg and Sen. Bernie Sanders. New Hampshire brought even worse news for Warren. She finished fourth in the state after a last-minute surge helped push Sen. Amy Klobuchar into third place.

Sanders has long cast himself as a staunch ally of labor unions and the candidate of the working class. But this week, he found himself at odds with one of the most powerful organized labor groups in Nevada, The Hill's Nathaniel Weixel reports. The dispute burst out into plain view earlier this week after news surfaced that the Nevada Culinary Workers Union had posted fliers criticizing the Vermont senator's signature Medicare for All plan. The fliers sparked blowback from Sanders's supporters, and union officials accused some of the senator's backers of harassing its members. Sanders responded to those claims on Thursday, denouncing online attacks against the union and its members, The Hill's Justine Coleman reports. "Harassment of all forms is unacceptable to me, and we urge supporters of all campaigns not to engage in bullying or ugly personal attacks," Sanders said. "Our campaign is building a multi-generational, multi-racial movement of love, compassion, and justice. We can certainly disagree on issues, but we must do it in a respectful manner." The Culinary Union ultimately declined on Thursday to endorse any candidate in the Democratic primary race, leaving the race for labor support in Nevada wide open ahead of its Feb. 22 caucuses.
