A majority disapproves of Comey's decision not to recommend charges

Hillary Clinton's lead over Donald Trump is down to just 3 per cent in the latest NBC/SurveyMonkey weekly tracking poll, after a week when her email practices came in for harsh public rebukes in Congress and from the director of the FBI.

Clinton leads Trump 47 to 43 per cent in the online tracking poll. A week ago, her lead was 48 to 43 per cent.

Following extensive coverage over FBI director James Comey's decision not to recommend criminal charges against Clinton for her email practices, 82 per cent of those surveyed said it was inappropriate for her to have used a private home server while at the State Department.

Comey slammed Clinton's 'careless' behavior even as he didn't ask the Justice Department to bring charges.

Hillary Clinton's lead over Donald Trump dropped to just three percentage points in a new NBC / SurveyMonkey poll

Clinton's lead has narrowed from a week ago, when it was 5 per cent

Comey's decision was opposed by a 56 per cent majority, and supported by 41 per cent of those surveyed.

The survey was conducted July 4 through July 10, as reporting over Bill Clinton's unannounced meeting with attorney general Loretta Lynch, Clinton's interview with the FBI, and Comey's stunning announcement reached a crescendo.

Clinton's lead over Trump is about 5 percentage points in the rolling RealClearPolitics average of major polls.

Both Clinton and Trump hold high unfavorable ratings in the 60s

Both Clinton and Trump continue to hold high unfavorable ratings. Clinton's unfavorable rating is 60 per cent, compared to 62 per cent for Trump, who has faced his own troubles as prominent members of his own party have announced they are skipping the Republican convention or offered tepid support for the nominee.

Not surprisingly, 78 per cent of Clinton's supporters back Comey's decision not to back charges, while 93 per cent of Trump's supporters disagree.
