In a Wall Street Journal/NBC News poll, Clinton is up nine percentage points over Trump, with the Democratic nominee garnering 47 percent of support compared to Trump's 38 percent among registered voters nationwide.
Both candidates continue to suffer from challenging unfavorable ratings, though Clinton has made strides improving her marks following the conventions.
Voters also weighed in on the controversy surrounding Trump after his comments on the Muslim family of a fallen United States soldier. In a four-way race, which includes Libertarian Gary Johnson and Green Party nominee Jill Stein, Clinton leads Trump 43 percent to 39 percent, while Johnson receives 4 percent, and Stein 3 percent, the poll conducted between August 1-3 shows.
On Friday, Ms Clinton praised the work of the press, calling it a "badge of honour" for Univision reporter Jorge Ramos to have been thrown out of a Trump press conference previous year.
"There's a reason they call the convention bounces a 'bounce.' They can shoot you up to an artificial high and then come down to reality", explained Clinton communications director Jennifer Palmieri, a longtime veteran of presidential politics.
Bad as those numbers are for Trump, they get worse when voters focus on the specifics.

According to RealClearPolitics, which keeps track of all major national polls, Ms. Clinton's average lead over Mr. Trump now stands at 6.8 percentage points. Fourteen percent (14%) of Republicans now prefer Clinton, while 11% of Democrats support Trump.
This is a damning statistic for Trump, considering that he was the front runner in the swing state polls just over a month ago. "First and foremost, the room is not filled just with journalists", Roland Martin, a journalist who moderated a panel prior to Clinton's remarks, told TIME.
Another battleground poll released Thursday - Michigan - also found Clinton holding a significant lead over Trump.
While she has given dozens of sit-down interviews - including one with Fox News this past Sunday - Ms Clinton's last proper press conference was in Iowa on 4 December, 2015, before a single primary vote was cast.
Kingston also argued Clinton would waste her time trying to flip Georgia blue. Another three percent (3%) prefer some other candidate, and four percent (4%) remain undecided. Forty percent who watched the Republican convention a week earlier said they were more likely to vote for Trump.
Mrs Clinton opened up a 15-point margin in the McClatchy-Marist survey, 48% to 33%, which was conducted as Trump feuded publicly first with the Pakistani-American parents of a slain USA soldier and then House of Representatives Speaker Paul Ryan, one of the Republican most popular and powerful figures.
Six hundred likely MI voters were surveyed in the poll.
