The national tracking poll was launched after Sunday night's second presidential debate, where Trump was pressed to explain his comments in a 2005 videotape about grabbing women's genitalia. "But this is locker room talk".
Yet despite the lewd tape, which has driven several leading Republicans - including House Speaker Paul Ryan - to distance themselves from their party's presidential nominee, Couric pointed out, many of Trump's core supporters are sticking with him.
In a four-way matchup, Clinton now has the support of 46 percent of likely voters, while Trump has 37 percent, Libertarian Party candidate Gary Johnson has eight percent and Green Party candidate Jill Stein has two percent. The only year voters got it wrong was in 1960 when they chose Richard Nixon over John F. Kennedy, according to 270towin.com.
Kathleen Willey said Bill Clinton assaulted her in the Oval Office, disclosing the claims in 1998 during the Monica Lewinsky scandal.
Sunday's debate, the second of three before the November 8 election, was remarkable for the brutal nature of the exchanges between Trump and Clinton, his Democratic rival. In this Atlantic-PRRI poll, for example, 90 percent of Democrats back Clinton while only 85 percent of Republicans back Trump.
In his campaign speech on Monday, Trump, who is trailing Hillary Clinton in the voter surveys, returned to his regular themes such as criticizing the status quo, which he says the former first lady represents, and his attacks on the media.
U.S. Republican Donald Trump has dismissed his vulgar sexual comments about women that surfaced on a video as "locker room talk", but his explanation did little to soothe the queasiness of Esther Rosser, a 71-year-old grandmother from Virginia. "When you're a star they let you do it", he is heard saying.
"I think the pressure may be getting to him", tweeted New York Times reporter Dave Itzkoff. Despite Trump's protests, six in 10 of those polled said CNN's Anderson Cooper and ABC News' Martha Raddatz did a good or excellent job moderating the contest. Her Republican opponent, Donald Trump, is in open warfare with members of his own party and is still reeling from the release of a 2005 video where he boasted about groping women.
For Trump's base which, Dean noted, largely represents the segment of the US population who've been "left behind by globalization", this election is about "giving the middle finger to Washington". He accused Bill Clinton of having been "abusive to women" and said Hillary Clinton went after those women "viciously".
Independents have usually favored Trump in polling, but the margin between how strongly they prefer Clinton or Trump predictably correlates to the margin between the two candidates. Monday's poll showed that Trump had only a 1-point edge over Clinton among people who identified as evangelicals. That's down from a 12-point advantage for Trump in July.
The poll was conducted October 8-10, 2016. The poll has a credibility interval of 3 percentage points.
