WASHINGTON, July 14 (UPI) -- As the effects of the FBI's investigation into her use of a private email system begin to sink in with the electorate, Hillary Clinton has seen her 6-point lead in one poll evaporate and Donald Trump pull ahead in another poll by 7 points.
The New York Times/CBS News poll released Wednesday shows Clinton tied with Republican Donald Trump nationally, at 40 percent apiece. Last month, the poll showed Clinton with a solid 6-point lead over her GOP rival.
A Rasmussen poll of likely voters shows Trump leading Clinton 44 percent to 37 percent. The poll has shown Trump with a lead over Clinton the last three weeks, but last week the lead was within the margin of error, 42 percent to 40 percent.
The Rasmussen survey shows Trump with the largest lead in the general election matchup against Clinton since October.
The reversal comes as voters more fully come to terms with Clinton's use of a private email server while secretary of state. Last week, FBI Director James Comey announced no criminal charges were recommended against Clinton, a determination the Clinton team celebrated as a legal victory.
The political fallout, however, has been sharp. Comey was harshly critical of Clinton's email system, calling it an "extremely careless" way to handle sensitive government information. He said in subsequent testimony before Congress that several of Clinton's assertions about her private email — that there was no classified information contained on the server and that she had turned over all of her work-related emails — were not backed up by facts uncovered by investigators.
The reaction from voters in the Times/CBS poll shows growing unease with Clinton's trustworthiness. Two-in-three voters, 67 percent, said Clinton is not honest and trustworthy, an increase of 7 points from last month, before the FBI investigation's conclusion.
While the Times/CBS poll shows a tie race, other polls have shown Clinton with a small, but consistent lead. The Real Clear Politics polling average nationally shows Clinton with a lead of 3.1 percentage points.
The New York Times/CBS News poll was conducted July 8-12. It queried 1,358 registered voters and has a margin of error of 3 percentage points.
The Rasmussen survey was conducted July 12-13. It surveyed 1,000 likely voters and has a margin of error of 3 percentage points.
