I agree with the commentary below. I think this poll is a knee-jerk reaction to Trump's poor showing at the debate. I think Biden is going to win but not by 14.
Mr. Biden, the Democratic nominee, leads the president, 53% to 39%, among registered voters in the new poll, which was conducted in the two days following the debate but before news emerged that Mr. Trump had tested positive for Covid-19. Mr. Biden’s 14-point lead compares with an 8-point advantage last month and 11 points in July, which was his largest of the campaign at that time. ...
Bill McInturff, a Republican pollster who directed the survey with Democrat Jeff Horwitt, cautioned that the poll was conducted during an unsettled moment after the caustic presidential debate—“a shock to the system,” he called it—and could reflect a temporary reassessment of views. “The public can be taking a moment to say, ‘What did I just see, and how do I feel about it?’” he said. Mr. Trump could regain ground, Mr. McInturff said, given that “he has a history of bouncing back to some set point.” ...
Messrs. Horwitt and McInturff said one factor was the debate, a decorum-destroying event in which the two candidates traded insults and continually talked over each other, with Mr. Trump interrupting his opponent more often. About three-quarters of voters said the event made no difference to their vote. But among the other 25%, a bigger share said the debate made them more likely to support Mr. Biden than Mr. Trump.
While 84% of Democrats said Mr. Biden did a better job in the debate, 54% of Republicans said so of the president. Overall, half of voters said Mr. Biden performed better, with a quarter saying Mr. Trump did. Some 17% said neither candidate did well.
Asked more broadly about the candidates’ personal qualities, voters by a two-to-one margin said Mr. Biden was better at displaying “the right temperament to be president,” 58% to 26%.
“It is clear that the debate, and Mr. Trump’s behavior during it, reinforced the negative side of Mr. Trump personally for many respondents,” said Mr. Horwitt. He said the president “lost the American people on style more than substance.”
