Despite poor showings in Iowa and New Hampshire, Biden's campaign has continued to express confidence about his standing in the field, claiming that diverse states such as South Carolina will propel his candidacy. He finished in second place in Nevada, the first state to hold a nominating contest that is not overwhelmingly white, but the latest survey shows that his support has fallen significantly among African Americans in South Carolina. 

Biden still leads in that category with 35 percent support, though the figure represent a 19-point decline since November. Steyer, who had just 2 percent support among that bloc last fall, now has 24 percent support. Sanders is close behind with 23 percent support among African Americans, which make up a majority of the Democratic electorate in South Carolina. 

Biden on Sunday attributed his decline in support among African Americans to Steyer's campaign, saying, "I think a lot’s happening in terms of the amount of money being spent by billionaires to try to cut into the African American vote."

The CBS-YouGov survey also found that three in 10 voters who supported Biden in November have switched their support, with about half of those now backing Steyer.

Sanders further cemented his status at the frontrunner to be the Democratic nominee with a decisive victory at the Nevada caucuses on Saturday. The win comes on the heels of a win in New Hampshire and as polls show him far outpacing his competitors. 

The CBS-YouGov survey was conducted among a sample of 2,000 registered South Carolina voters between Feb. 20 and Feb. 22. It has margin of error of 5.5 percentage points.
