Although Clinton held a 3-point edge in the poll early this month, she had expanded that lead to as many as 7 points in recent weeks. 
 
Trump has sought to make up ground with a series of carefully prepared speeches going after Clinton.
 
Still, nearly a quarter of respondents, 24 percent, said they think Clinton will likely win "in a landslide," and another 29 percent think she'll win at least narrowly.
 
Meanwhile, 19 percent think Trump will win narrowly, a slight uptick from previous polls, while another 9 percent think he'll win in a landslide election. Nineteen percent are not sure.
 
Clinton has a similar edge when third-party candidates are included in the polling. When they are factored in, she leads Trump by 4 points, 42 percent to 38 percent, among registered voters.

MORE takes 6 percent support in that scenario, and Green Party nominee Jill Stein draws 4 percent, while 2 percent would pick someone else, 7 percent are not sure yet and 3 percent would probably not vote.
 
The poll of 906 registered voters was conducted online Aug. 19–23 and has a margin of error of 4.1 percentage points.
