Normally, exit polling aren't too problematic, but exit polls in this election when "vote in person" vs. "vote by mail" has been a matter itself of intense partisan division, well... There's a fairly obvious built-in bias compared to the electorate at large.
> I was reading an analysis today that suggested Dems may continue to lose these groups - and they will be losing them to the Republicans ( [2] but note the source and that's it opinion and give the appropriate grain of salt). Given how uncomfortably close 2020 has been for the Dems, I would not rest on my laurels and assume we'll just continue to come out ahead in these groups.
I'm not sure there is a grain of salt large enough for "analysis" from the Editor-in-Chief of the Washington Examiner which rests on no apparent actual data. That said, I think complacency is never good, and I think the Democratic Party should be active asking how it can serve all kind of communities better, including black, hispanic, and other racial/ethnic minorities (and the working class generally, and...)
But there's a difference between that and believing that there is clear (or even strongly suggestive) evidence of a particular problem with certain particular communities (I think there is, but more with the working class than race/ethnic minorities, right now; but I think that means we need greater additional effort in the "working class" area, not an absence of it in the others.)
