The poll was conducted in the two days after the unruly and insult-filled Sept. 29 debate, but before Trump tested positive for Covid-19 and was hospitalized Friday at Walter Reed National Military Medical Center.

The Democratic nominee is now ahead of Trump by 14 points among registered voters, 53 percent to 39 percent — up from his 8-point lead in the previous poll before the debate.

That 14-point advantage represents Biden’s largest lead in the NBC News/WSJ poll during the entirety of the 2020 presidential campaign; his previous high was 11 points in July…

The biggest declines for Trump in the poll come from seniors (who are now backing Biden by a 62 percent-to-35 percent margin) and suburban women (58 percent to 33 percent).

And men 50 years and older moved from a 13-point advantage for Trump in the pre-debate NBC News/WSJ poll, to a 1-point advantage for Biden in this latest poll.
