This analysis is quite poor. Calls Arizona a disaster for rats then puts it in their column. The idea that early returns gives you a strong indication of of who will win leaves something to be desired. Maybe if you knew which part of the state you could but as presented here. Rubbish
Why is IA and AZ blue? Trump is ahead in both states.
I agree, this analysis is weak. It doesn’t distinguish between states that track registration and states they are modelled.
