Skya Rhen has already posted a thread about the top numbers from the poll

showing Biden with 36% and his two closest rivals, Warren and Sanders, nearly tied with less than half of Biden's support in the state.

I wanted to check the poll's internal numbers.

Despite attacks on Biden made in attempt to lower his support among black voters, he still leads with them 45% to 15% each for Sanders and Harris. (That page about the poll doesn't provide the exact percentage for the other candidates, just a graph, but judging by the graph, Warren's support among black voters in SC might be in single digits, with other candidates doing worse. Looks like Booker probably is getting only about 5% support there.)

Among white voters, Warren has a narrow lead over Biden, 26% to 24%. Sanders is third with 16%.

Again, the poll data available on that page doesn't give a percentage for Biden's support among the youngest group of voters, but it looks like it's about half the support Sanders has, so probably around 15%. I'm not surprised that Sanders and Warren are leading with that group, given their plans for free college and forgiving college debt.
