Exit polling was basically meaningless in this election because mail in votes were the deciding factor.

The key problem with exit polls (in non-pandemic years) is that they are non-representative until the whole vote is collected and they can be re-weighed.

"exit polls are eventually weighted to match the final results, but that only happens after the election is over. On election night itself, the numbers are reweighted as more data becomes available, but what you’re seeing is still subject to a lot of uncertainty"

Yeah, since about 2000 it's been shown to be really unreliable in the US. Heavily weighted towards democrats for much of the same reasons that makes normal polling unreliable now.

Considering the trend for people to be socially canceled, scorned, and shamed for supporting the "wrong" candidate, yes I think exit polling (and all polling for that matter) are not working. People are much more likely to either decline to respond, or they will lie.
