So the AZ part is trash but IN and especially FL are fine? That’s really being hackish
I don't think anyone is saying that (well, no one who knows what they're talking about). I think that what people are saying is that the crosstabs for Arizona make less sense than the crosstabs in the other two polls, particularly in light of the early voting numbers thus far.
Personally I don't think any of these polls are 'better' in terms of likelihood of being correct, though I do think that their turnout models are conflicting. These polls would be higher quality if their models were more consistent and if they weren't purely conducted online.
