There is rather too much data mining going on within polls that we decided not to believe anyway.
The Hispanic improvement . . . the improvement among blacks . . . the past gold standard for those measurements was exit polls. Not likely to remain gold standard this year, though I’m sure it will be quoted.
We may have zero data of any value upcoming, other than the final vote count. This will make data people angry, and broke. Hard to sell advertising if all you have is opinion.
It was the Dem’s bastion, the NY Times, saying about their own poll that Biden is showing weakness with Hispanics in TX. They see this and they’re warning about it. They also warn that they see Biden is under-performing Clinton in deep blue (pre-riot) PA Philly by 10% and Trump is over-performing his 2016 exit polling there.
When these ‘nuggets of truth’ slip out from the other side, about their own side, it’s worth taking into consideration.
