WASHINGTON — Our new NBC News/Marist poll of South Carolina captures all of the different ingredients that could result in Bernie Sanders wrapping up the Democratic nomination in just a month.
One, you have the winner of Iowa and close second-place finisher of New Hampshire (Pete Buttigieg) sitting at just 4 percent among likely African American Democratic primary voters. Call it the Reverse Obama — the Iowa winner unable to play in the South and with African American voters.
Two, you have the slight Democratic leader in South Carolina (Joe Biden) at just 27 percent among all likely South Carolina Democratic primary voters after his fourth place in Iowa and fifth in New Hampshire — much lower than Hillary Clinton's 74 percent that carried this state in 2016.
Three, you have one billionaire without a single delegate so far (Tom Steyer) at 15 percent and peeling away support from Biden — after spending some $20 million over the South Carolina airwaves.
Four, you have another billionaire who's not even on the ballot in South Carolina (Michael Bloomberg) who continues to suck up oxygen in the race and who will make his second debate appearance tonight.
Five, you have candidates mired in single digits in South Carolina (Buttigieg, Elizabeth Warren, Amy Klobuchar) who aren't leaving this Democratic race anytime soon with Super Tuesday just a week away.
And six, you have Sanders trailing Biden by only 4 points in South Carolina and improving demographically across the board from 2016 — he's at 20 percent among African Americans in South Carolina after getting 51 percent of the Latino vote in Nevada.
Add them all up, and you see not only why Sanders is the Democratic front-runner and why he could put away the Democratic race on Super Tuesday.
You also see how he might even win in South Carolina, a state he lost by nearly 50 points in 2016.
As far as tonight's debate goes (more on that below), if a "Stop Bernie" effort doesn't work, then it's either fast consolidation or a slow coronation for Sanders.
Breaking down our South Carolina poll
One important point from our NBC News/Marist poll of South Carolina: It was conducted Feb. 18-21 - so all before the Nevada caucuses, which Sanders won by more than a 2-to-1 margin.
Here are the overall numbers among likely Democratic primary voters: Biden 27 percent, Sanders 24 percent, Steyer 15 percent, Buttigieg 9 percent, Warren 8 percent and Klobuchar 5 percent.
Among likely African-American Democratic primary voters: Biden 35 percent, Sanders 20 percent, Steyer 19 percent, Warren 7 percent, Buttigieg 4 percent, Klobuchar 2 percent.
Among likely white Democratic primary voters: Sanders 26 percent, Biden 18 percent, Buttigieg 17 percent, Steyer 10 percent, Warren 9 percent and Klobuchar 9 percent.
Also in the poll: 72 percent of Sanders backers say they strongly support the Vermont senator, versus 61 percent for Biden's supporters and 60 percent for Steyer's.

Dispatches from NBC's campaign embeds
Priscilla Thompson reports that Pete Buttigieg is changing up his stump speech to lean into a humility message: "'Campaigning is about humbling yourself,' he told the crowd of roughly 100 people. 'It is especially humbling to be asking for the trust of African-American voters,' Buttigieg said, outlining the significance of a vote 'that was hard won through blood and sweat." All this led him to say, "I know that when I ask for your vote, I'm asking you to trust your life and your family's future to me.' The former mayor went on to discuss, in overarching terms, his record in South Bend -- again emphasizing humility. 'I can talk about all the things that we did together that we're proud of, but being mayor too is an exercise, not only in hope but in humility, he said. 'I was humbled, again and again by the challenge, and by the intractability of some of the issues that we faced, knowing that we have so much more work to do to confront the impact of institutional racism.'"
