Okay comparing 538 averages and the NYTimes current count. Not everything is fully in of course, so some grain of salt. Kinda of rough estimating from remaining votes, by eyeballing it.
And of course, the 538 average isn't entirely based on polls and is partly based on demographics and past voting patterns. So it seems generally more accurate than a simple average of polls.
But why is the average if anything, understating Biden in Colorado, the same in California, probably will be pretty close to right in Georgia, about right in Virginia, about right in Minnesota, only a tad off in New Hampshire, about right in Maine, about right in New Mexico, about right in New Jersey (at the moment only 0.1 off, but with a lot left to count) a bit off in Oregon, about right in Washington, probably right in Illinois (hard to tell, they had a lot left to count in Cook, it could be understated), the same with New York (lots of ballots still out), and the small New England states are much the same.
In redder states, it seems about right in Louisiana, probably Utah considering how many remain to count in Salt Lake City, maybe South Carolina, about right in Oklahoma. Kansas might be right or a bit off. About right in Nebraska.
The polling error seems to be particularly focused, in mainly the critical states. The Blue wall, Ohio, Iowa, Florida, NC, Texas and some, but not all of the redder states. A lot of southern states where Biden isn't hitting the mark, and some of the Interior west states.
Nevada might be a error, depends on how the final 10% splits. It could end up dead on. Arizona has the most unpredictable final count, but it could also be basically on.
So why is the polling error, mostly surgically located where it hurts Biden and the Democrats the most?
Anyway, as for the blame game, I think both sides honestly have good points. Progressives did run behind Biden, and some conservative Democrats did outperform Biden. There are clearly people deliberately splitting their ballots based on ideological positioning and rhetoric.
But Biden and Democrats also ran behind a lot of progressive stuff on the ballot, polling has been pretty clear that Americans want progressive stuff by very large margins (not always specific stuff like M4A, but a lot of stuff on the Democratic party platform) and they hate what Republicans govern on, and well, there just seems to be a mass messaging strategy mishap to let Trump get it this close, and for all this ticket-splitting to happen.
But generally, looking at the 538 averages for states, makes me think better about their predicting. The added demographic and past voting pattern has them not get it as wrong as a simple poll average (which is way worse). And a lot of the polling firms, in particular, were really really off. . But there are still some clear errors, and in many of the same states.
I will hold off on my national polling takes, since there doesn't seem to be a clear indication of how many ballots remain.
Will North Carolina join the wave?
Unsure. The election people seem to think it is still lean/likely Trump
The Elect Project estimates 478,828 outstanding ballots across the state, of which
231,035 are Democratic
87,224 are Republican
3,000 are Minor Parties
157,569 are Non Partisan affliation.
The current Count is
2,732,120 Trump
2,655,383 Biden.
That is a gap of 76737. So more than enough, simply by adding the outstanding Democrats, vs outstanding Republicans, even assuming an even split of NPA.
BUT not all of those will get returned, and some of those would have already voted on election day, instead of mailing them in, and so may or may not have been counted, or counted as a provisional vote.
The North Carolina State Board of Elections, estimates a much lower 116,000 absentee by-mail ballots to count. Which Biden would need to win by a much larger percentage, to win. And Cal Cunningham would need to sweep to win.

According to the North Carolina State Board of Elections, there are about 116,000 absentee by-mail ballots that could still be counted.
The roughly 116,200 outstanding absentee-by-mail ballots breakdown as 37 percent Democratic, 39 percent unaffiliated, and 23 percent Republican.
Roughly 57 percent (65,900) of the outstanding ballots are pegged to the 25 counties where Biden currently leads, according to NCSBE data. Those counties also make up the nine most populous counties in the state (Wake, Mecklenburg, Guilford, Forsyth, Cumberland, Durham, Buncombe, Union, New Hanover).
The 100 bipartisan county boards will hold meetings to count the remaining provisional and absentee ballots and add them to unofficial election results on the Election Night Reporting website.
The Board of elections is more likely to be right, but many states have underestimated how many ballots would be returned in some states. I've seen multiple other estimates of NC results. The 94-96% remaining from sites like the ABC, and NYTimes, would be more than the North Carolina Board of elections is estimating, but less than the total outstanding. Thought some of those may be election day votes uncounted for reasons. And when the needle was there, it was favouring Trump.
So the answer is generally we don't know.
