South Carolina represents a major test for candidates among voters of color, as black voters make up 60 percent of the electorate in the state — a major shift from previous contests in the majority white states of Iowa and New Hampshire.

Biden leads among black likely voters in the poll with 43 percent, while Sanders polls at 20 percent. Of note is improvement for Buttigieg, who received support from 16 percent of black respondents. Buttigieg has struggled to garner support from the African American voting bloc in the past.

"[O]ur poll has this as a close race, with Biden only ahead by 2 points and Sanders inside the margin of error. With just 10 days to go, Biden needs to hold this lead and prove he can win if he wants to make a play on Super Tuesday,” said poll director Jonathan Dyck in a statement.

The UMass Lowell poll was conducted between Feb. 12-18, with a pool of 400 likely South Carolina primary voters. The margin of error is 7.5 percentage points.
