The Post and Courier noted that Harris and Sanders' support has remained steady in the state since February. Biden, on the other hand, has experienced a surge in support since officially launching his presidential campaign in late April. 

“He’s always been popular in South Carolina and always maintained good relationships here, so people were really excited about him getting in,” Kenneth Glover, chairman of the Orangeburg County Democratic Party, told The Post and Courier.

Polls have increasingly shown that Biden and Sanders are the early favorites among the field of candidates vying for the 2020 Democratic presidential nomination and recent surveys have shown Biden with a substantial lead over Sanders. 

A Morning Consult poll released last week found Biden had a 21-point lead over Sanders nationwide. 

The Post and Courier-Change Research Poll was conducted between May 6 and May 9 among a population of 595 likely South Carolina primary voters. The margin of error is four percent.
