The poll still shows Biden leading the pack with 24 percent support among likely South Carolina primary voters. But that represents a significant decrease from a similar Winthrop University poll from September that showed the former vice president with a 20-point advantage in the state.

South Carolina, which holds its presidential primary Feb. 29, is the first state to vote in the nominating contest in which a majority of the Democratic electorate is black.

Biden has long cast the Palmetto State primary as something of a firewall for his campaign; a contest in which his strong support among black voters could help propel his presidential bid into Super Tuesday on March 3, even after middling finishes in Iowa and New Hampshire.

But the Winthrop University poll suggests that Biden’s early setbacks in the primary race may be eroding his momentum, even in a state that his aides have cast as rock-solid for his campaign. 

Still, there are signs that the race in South Carolina remains fluid. While most respondents to the poll — 55 percent — said they are “very sure” who they will vote for, 43 percent said they might still change their mind ahead of the primary.

The Winthrop University poll surveyed 443 likely Democratic primary voters in South Carolina from Feb. 9-19. It has a margin of error of 4.7 percentage points.
