Suffolk found Trump with the support of 44% of likely North Carolina voters, a statistically insignificant three points better than Clinton's 41%. That's virtually unchanged from a month ago.
Hillary Clinton, the Democratic candidate for president, on Monday said she took seriously the threat that Russian Federation could interfere with national elections in the United States and that her campaign rival is fixated on dictators.
Clinton and Trump both get the support of 47 percent of likely voters in a head-to-head matchup, according to the Quinnipiac poll, released Thursday.
That's cut Clinton's lead over Trump by more than half over the past month.
The two remain tied when the most prominent third-party candidates are thrown into the race, with Trump and Clinton drawing 43 percent apiece.
Those numbers are also basically the same as Quinnipiac's August poll, though Johnson has moved up a point and Stein is down one.
The Quinnipiac University poll was conducted August 29-September 7 using phone interviews with 761 likely voters in Florida, 751 likely voters in North Carolina, 775 likely voters in OH and 778 likely voters in Pennsylvania.
But Trump's largest lead came in Iowa, where the Ipsos poll showed him up by 3 points. With Libertarian Party nominee Gary Johnson included, neither Clinton nor Trump eclipsed 45% in any of the four battleground states.
The pollster's takeaway here is that Clinton has lost her post-Democratic convention polling bump. A Clinton victory in the state sharply narrows Trump's potential path to 270 electoral votes.
New polling released Thursday shows a competitive presidential race in some of the most crucial swing states.
Pennsylvania's 20 electoral votes make it a valuable prize, and winning the state has been a key hope for Trump's campaign.
Meanwhile, Trump takes 59 percent of white voters, to 36 percent for Clinton.
Trump's campaign fired back at Clinton after her session with reporters, saying she was resorting to "unhinged and dishonest" attacks.
The numbers among different subgroups have larger margins of error than those in the overall poll.
The divide persists despite recent efforts by Trump to reach out to nonwhite voters, particularly African-Americans.
