But things started to shift in late January, when Warren's stock began to fall and Biden and Sanders started running within a few points of each other in Texas. NPR has called it "so crucial".
And the state should matter a lot.
An emotional Clyburn said he was "fearful" about the state of the country and pointed to Biden as the candidate to lead the party.
That endorsement, which came Wednesday, may have bolstered Biden's appeal ahead of the fierce primary race in the state on Saturday.
"I am scared, if we can not pull this party together, if we go to one of those extremes, we take a awful risk of re-electing Donald Trump". But Warren spent most of her time like she was running to be Fidel Sanders running mate by obsessively attacking Michael Bloomberg who is not even on the SC ballot.
The reason: Super Tuesday, with 30 percent of all available delegates, is three days later.
It was different in earlier cycles.
While Biden remains in the lead in surveys of the state and said during yesterday's debate he plans to win the primary, Sanders has been gaining ground after a series of wins across the three previous primary states.
"The rules are very clear: the person who will be nominated for president will be the person who will have the majority of the votes", Pelosi said. "Here's President Obama." It then uses clips from Obama reading his 1995 memoir out of context to attack Biden on race. That made Tuesday's debate likely the last chance for some candidates to save themselves and alter the trajectory of the nomination fight ahead of Super Tuesday on March 3.

A group called Wet'suwet'en Strong: Hamilton in Solidarity, claimed responsibility for the blockade. He said the prime minister's plea for patience last week prevented police from acting sooner.
Virginia is one of 14 states holding primaries Tuesday.
Confronted with his diminishing support among black voters during the tenth Democratic debate on Tuesday, Biden insisted he had "worked like the devil to earn the vote of the African American community", vowing to "win South Carolina" with the help of its black voting bloc.
Senator Elizabeth Warren, for example, will campaign in SC, but she will also have a rally on Thursday in San Antonio and stop in Los Angeles. Cash-strapped Biden is also counting on a wave of free media should he win SC.
Elsewhere in the debate, Senator Elizabeth Warren, 70, went for the jugular again with former New York City mayor Michael Bloomberg, 78, again bringing up the non-disclosure agreements in settlements with female employees at Bloomberg LP. Buttigieg sits in second with 26, followed by Biden, Warren and Klobuchar. Next, she chartered a plane to get to North Dakota, Oklahoma, and Arkansas.
Tuesday's event was the final debate before the SC primary and Super Tuesday, when voters in 14 states hit the primary polls.
But it is almost impossible for anyone to raise money, make ads, and purchase ad time over a weekend in a way that could even remotely make a dent in places such as California and Texas, Super Tuesday states.
And as part of its apparent outreach to African-American voters, Donald Trump's re-election campaign announced yesterday that it's opening "engagement centers" in 15 states, hoping to boost "Black Voices for Trump". New Hampshire set up the race.
Bloomberg referred to reports that USA intelligence officials believe Russian Federation is trying to help Sanders.
