Clinton has the advantage among African Americans (84 to 7 percent), voters ages 18-29 (55 to 32 percent) and women (52 to 37 percent). The margin among Latinos will be released later on Sunday.
Trump, meanwhile, is ahead among whites (50 to 37 percent) and men (46 to 39 percent), and the two candidates are tied among independents (36 percent each).
In a four-way ballot test - including Libertarian nominee Gary Johnson and the Green Party's Jill Stein - Clinton gets 41 percent, Trump 35 percent, Johnson 11 percent, and Stein 6 percent.
"The more things change, the more they stay the same," says Democratic pollster Peter Hart, whose firm helped conduct this poll with Republican pollster Bill McInturff. "Things haven't changed an awful lot."
McInturff agrees. "Our overall ballot is very stable, and the contours of this election are becoming stable."
