Biden said Tuesday on the debate stage that he expects to win in South Carolina, the first state on the primary calendar to have a significant African American population, following disappointing finishes in Iowa and New Hampshire. He came in a distant second behind Sanders in last weekend's Nevada caucuses. 

The survey is based on 650 respondents, through a mixed methodology of telephone response, online and online panel voters. It was conducted between Feb. 17 and 25. There is a margin of error of 3.8 percentage points. 

The results of the survey were not weighted for age, sex or ethnicity, pollsters said. Three percent of respondents were under 25, 14 percent were under 40, 20 percent were under 54, 21 percent were under 64, and 43 percent were 65 or older.
