South Carolina: Biden 28, Sanders 23, Steyer 18, Warren 12

This poll was finished before Sanders coasted to a win in the Nevada caucuses Saturday night — though most South Carolina voters told us the Nevada results would not impact them.

Although Biden continues to lead among African-Americans — who make up a majority of the state’s Democratic electorate — his support with black voters has declined 19 points since the fall.

Biden has lost ground with white voters, too. He led with whites in November, but Sanders does now.
