Poll: Hillary's lead over Trump shrinks to three points after controversial week

While a majority of American voters (56 percent) disagree with Comey’s recommendation that Clinton should not be prosecuted by the Department of Justice, these attitudes break sharply by candidate support. Though Donald Trump’s supporters nearly unanimously (93 percent) disagree with the FBI’s conclusions, a majority (78 percent) of Clinton’s supporters agree that she should not be prosecuted. A notable two in 10 of Clinton’s supporters, however, said they disagreed with Comey’s decision as well.

The email controversy seems to have a meaningful impact on voters’ impressions of the presumptive Democratic nominee as 66 percent of voters now say she is not honest and trustworthy — including a third of her own supporters. This issue was a sticking point for many Democrats during her primary campaign run and is often attributed in part to Bernie Sanders’ ability to remain somewhat competitive with Clinton.

While it is unclear what lasting impacts the investigation could have on her bid for presidency, the email investigation’s findings do not appear to have moved Clinton’s favorability ratings significantly.
