You could probably convince me that the race has tightened by half a point. On the other hand, there had been a bit of a state poll vs. national poll gap, and Biden got some pretty good state polls this morning. https://projects.fivethirtyeight.com/polls/ 

As @Nate_Cohn wrote yesterday, there are also some reasons to think the race might tighten a bit. Indeed, that's what our model predicts (it has Biden winning the popular vote by ~8, not ~10). But Trump needs it to tighten by *more than a bit*. https://www.nytimes.com/live/2020/presidential-polls-trump-biden#trumps-best-day-of-polling-since-the-debate

There's a ton of national polling so no one poll is going to influence our average much. And there's nothing intrinsically wrong with the IBD poll. But that won't stop some people from looking only at that poll and not the many other polls in the average. https://twitter.com/joshtpm/status/1318910415989071873?s=20

Looking at the polling average vs. cherry-picking polls is the lowest bar to clear. If someone isn't able to do that, then maybe they have valuable insights about other topics but they don't know what they're doing on polling stuff.
