"Results are among registered voters. Respondents who said they didn't know who they would vote for or who declined to say are not included."
The NYT absolutely wants a horserace, and likely a Trump win, and their coverage will be designed to produce that result, or at least that impression among their audience.
Obviously these numbers (if they are remotely accurate) are not good news for Biden (or the United States). Biden is not a popular President. (No matter that I think he should be.) But I certainly don't think they spell certain doom for Biden in Nevada.
The same is true here that is true of all modern polling. When it comes to polling, all likely Trump-voters will unreservedly support Trump and denounce Biden. Many likely Biden voters will be critical of Biden. If he wins (as I hope he will) Biden is going to win undecided voters overwhelmingly.
I tend to lean in the opposite direction because negativism and grievance sells.
