The poll reveals that Sanders struggles with recognition in South Carolina, where only 44 percent of respondents agreed that they know him “very well,” compared to 70 percent who said the same of Clinton.

South Carolina voters also question the preparedness of the Vermont senator to be president, with only 51 percent of respondents saying he is “ready” to be commander in chief, compared to 80 percent who said Clinton is prepared for the job.

Despite his shortcomings in those categories, Sanders is still seen as the more trustworthy candidate, with 75 percent of respondents agreeing he is “honest and trustworthy,” compared to 60 percent of Democrats who said Clinton can be trusted.

The CBS News poll, which surveyed 1,315 registered voters online from Feb. 10 – 12, has a margin of error of 8.7 percent.
