I suspect 538 and similar will be defend their models and claim almost all of the "missed" states were within their expected polling error. They can also point to the high number of 1st time voters overwhelming their "expected voter" model.
In their more introspective moments they'll need to admit that the last 3-4 times polling significantly missed it was always in one direction. The misses have not been randomly distributed and polls tend to undercount rural, conservative Republicans. Maybe they don't answer the phone, maybe they are hard to find for another reason but they are consistently undercounted. Time to fine-tune the sample method rather than just complain you are being unfairly blamed for your misses.

In 1938 Neville Chamberlain declared "Peace in our time", Superman first appeared in Action Comics, Seabiscuit beat War Admiral ....... and C.a.l last won the Rose Bowl.
