Only 33 percent of people view Democratic presidential candidate Hillary Clinton favorably, a new CBS poll found. The Democratic front-runner also has a record high 53 percent unfavorability rating. 61 percent of voters also say Clinton is not honest.

Asked about Clinton's use of a personal server and email address during her tenure at the State Department, 71 percent of registered voters said this was not appropriate and 59 percent were dissatisfied with the explanations she has given.

Despite her high unfavorability ratings, Clinton continues to retain the lead in this poll, which found that she is 19 points ahead of Sen. Bernie Sanders, I-Vt.

If Vice President Joe Biden does not enter the race, Clinton's lead over Sanders grows, the poll released Sunday found.
