Oprah Winfrey's well-publicized appearances with Barack Obama have raised Obama's visibility, especially among African Americans. Roughly a quarter of Americans (26%) say they have heard more about Obama recently than any other presidential candidate, up from just 10% in November. Meanwhile, though Hillary Clinton remains the most visible candidate overall, the proportion citing her as the candidate they have heard the most about fell from a high of 61% in November to 41% in the current poll.
Far more African Americans cite Obama (51%) than Clinton (27%) as the candidate they have heard the most about recently. In November, these figures were roughly the reverse, with 50% naming Clinton and 15% Obama. Whites were also more likely to name Obama this month compared with last month, but the increase was not as great (23% this month up from 9% in November).
