LEADING THE DAY:

COLUMBIA, S.C. – Joe Biden Joe BidenBiden leads Trump by 36 points nationally among Latinos: poll GOP set to release controversial Biden report Can Donald Trump maintain new momentum until this November? MORE needs a win. And he's hoping that South Carolina will give it to him.

Since voting began in the Democratic nominating contest earlier this month, the former vice president has seen his long-held frontrunner status slip away and questions about his electability emerge. What's more, he's still competing with several candidates for the support of moderate voters, while his chief rival, Sen. Bernie Sanders Bernie SandersNYT editorial board remembers Ginsburg: She 'will forever have two legacies' Two GOP governors urge Republicans to hold off on Supreme Court nominee Sanders knocks McConnell: He's going against Ginsburg's 'dying wishes' MORE (I-Vt.), has largely run away with the progressive vote.

But his campaign argues that South Carolina will be different. Biden's support among black voters remains strong and black voters are expected to make up a majority of the primary vote in the Palmetto State. He's also leading the pack in polls here -- by double digits in some -- and his allies say that a win on Saturday will give him the momentum he needs to emerge as the clear alternative to Sanders heading into Super Tuesday.

But how much the South Carolina primary will weigh on the rest of the race is unclear. Sanders is the favorite to win in delegate-rich Super Tuesday states, like California and Texas, and Biden is still facing a crowded moderate lane that has made it difficult for any one candidate to consolidate support. He'll also have to contend with 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 -- and his immense personal fortune -- on Super Tuesday, a factor that threatens to further divide the centrist vote in the primary.

Sanders, who has supplanted Biden as the frontrunner following back-to-back wins in the New Hampshire primary and Nevada caucuses, is under no illusions about Biden's strength in the Palmetto State, opting to spend primary day in Virginia rather than stick it out in South Carolina. But that didn't stop him from going after Biden during a rally in Spartanburg on Thursday, in which he insisted that the former vice president would be a general election liability for Democrats if he wins the nomination.

"I don't believe that Joe can beat Trump when he voted for the war in Iraq," Sanders said. "I don't believe Joe can beat Trump when people understand he voted with NAFTA and [Permanent Normal Trade Relations] with China. Terrible trade agreements that cost us millions of jobs."

Regardless, Biden and his allies are confident that South Carolina will be a turning point for his campaign. We'll find out on Saturday.

FROM THE TRAIL:

While all eyes will be on South Carolina on Saturday, most of the candidates will already have their sights set on the southern Super Tuesday states. Bloomberg will spend his Saturday morning campaigning in the Washington, D.C.,-suburb of Tysons Corner, Va., before he travels to Charlotte, N.C. Sanders will hold rallies in Norfolk, Va., and Virginia Beach on Saturday afternoon and evening. Sen.

Barack Obama Barack Hussein ObamaDemocratic Senate campaign arm outraises GOP by M in August A federal court may have declared immigration arrests unconstitutional Blunt says vote on Trump court nominee different than 2016 because White House, Senate in 'political agreement' MORE wisely chose Joe as his partner in the White House," Kaine, the 2016 vice presidential nominee, said in a statement.

The Hill's Scott Wong and Cristina Marcos report that centrist congressional Democrats supporting moderate presidential contenders are pushing back on Sanders's argument that the candidate with the most delegates heading into the convention, even if it's not a majority, should be the party's nominee.

"The PAC donation process -- with its expectations of exchanging favors and time for money -- renders public service, which should be among the nation's most noble professions, dangerously close to the oldest profession," Gaetz said.

ONE FUN THING:

PINT SIZED FAN: Former 2020 presidential contender and Warren supporter Julián Castro brought his young son, Cristián, along to a campaign event for the Massachusetts senator recently, and it looks like the younger Castro is all in for Warren!

The youngster smiled wide for the camera during Warren's speech and enthusiastically clapped his hands.

Check out this video from Castro's communications director, Sawyer Hackett:

I just want to take a minute to acknowledge this video I took of Cristián Castro enjoying @ewarren’s speech. pic.twitter.com/wfljkyBegW — Sawyer Hackett (@SawyerHackett) February 28, 2020

"Could he be saying 'it's time for a wealth tax?'" Warren's national Latinx outreach director Jonathan Jayes-Green, replied on Twitter to the video.

We don't know about that, but it looks like Cristián is feeling pretty good ahead of South Carolina.

We'll see you next week with a Super Tuesday preview!
