As an FYI, there have been a fairly high number of polls with partisan sponsors in the presidential race this year. (Usually these are more common in races for Congress.) We DO include these polls in our averages, which is a change from the past, but with an adjustment.
Namely, we use a stricter house effects adjustment; the model assumes that these polls are biased until proven otherwise. And it weights them less.
However, for boring technical reasons, the model wasn't catching all the partisan polls and adjusting them like it was supposed to.

So as an FYI, we fixed that tonight, which slightly changed the averages in some states. Also, here is our newly-updated polls policy, which explains what is considered a partisan poll. fivethirtyeight.com/features/polls…
Polls sponsored by media organizations are generally *not* considered partisan, even if that organization has a clear viewpoint. But we make an exception if they cherry-pick or selectively release data, as OANN has been doing. 
OANN is currently the only organization that we've had to apply this policy to, but please be aware that we'll also apply it to other sponsors that selectively release data to the benefit of one candidate or party, which clearly qualifies as partisan behavior.
