How to handle polls that say Americans don't trust your candidate? Easy peasy! [View all]

While Clinton remains strikingly dominant in the Democratic field, the poll shows that her numbers have dropped significantly across several key indicators since she launched her campaign in April.

A growing number of people say she is not honest and trustworthy (57%, up from 49% in March), less than half feel she cares about people like them (47%, down from 53% last July) and more now feel she does not inspire confidence (50%, up from 42% last March).

DICKERSON: Here's the question that -- when I talk to Democratic strategist, people even are anxious for her to be president. They say she can list a lot of things. The biggest problem for her is trust. The voters in the polls have shown this. Voters do not trust her. How does she overcome that?

MOOK: Well, first of all, there -- no poll shows that voters don't trust Hillary Clinton.

DICKERSON: They don't find her honest and trustworthy.

MOOK: Well, no poll says that.
