Hillary Clinton's October momentum came "to a halt" in the QU swing state poll, according to a Wednesday afternoon release, which said the Democrat had seen her leads shrink slightly in Florida and North Carolina. Trump, meanwhile, vaulted into a 5-point lead in Ohio in the latest poll.
"No one has been elected president since 1960 without carrying two of the key swing states, Florida, Ohio and Pennsylvania. And, this year, North Carolina has been added to the mix. All four of these key states remain close entering the final days," Peter Brown, assistant director of the Quinnipiac University Poll, said in a release.
The most recent poll was conducted between Oct. 27 and Nov. 1. On Oct. 28, the FBI disclosed that it was probing newly discovered emails related to Clinton's use of a private server, potentially altering the course of the race.
Here are the results of the Quinnipiac four-way poll, which included Trump, Clinton, Libertarian Party candidate Gary Johnson and Green party candidate Jill Stein.
Florida: Clinton had 46 percent to Trump's 45 percent, with 2 percent each for Johnson and Stein. Clinton had led Trump 48 - 44 percent on Oct. 17.
North Carolina: Clinton had 47 percent to Trump's 44 percent, with 3 percent for Johnson. Clinton had led Trump 47 - 43 percent on Oct. 27.
Ohio: Trump had 46 percent to Clinton's 41 percent, with 5 percent for Johnson and 2 percent for Stein. Clinton and Trump were tied 45 - 45 percent on Oct. 17.
Pennsylvania: Clinton had 48 percent to Trump's 43 percent, with 3 percent for Johnson and 3 percent for Stein. Clinton had led Trump 47 - 41 percent on Oct. 17.
According to Quinnipiac, the margin of error was 3.9 percentage points in Florida and 4 points in the other three battleground surveys.
