Something else interesting about AZ
Rs now have the lead in Maricopa Co (the big one)
But check this out
Rs 541,263 (with 59.3% turnout)
Ds 535,246 (with 65.9% turnout)
Despite the fact that Dems are turning out 6.6% more of their voters, they still trail. As mentioned in a post above, I think "cross-overs" are going to be a factor in this election, based on how any non-Rs show up to Trump rallies. They keep tract of this through ticket registration and his rallies get ~31% non-Rs (Dems, indies/non-affiliateds, libertarians, whatever). Which is quite remarkable if you think about it. Polling does not account for these people. And even regression models based upon EV + party registration (which IMO are way better than polling) cannot account for this. This number is going to be statically significant in 2020 "like you've never seen before." And it is going to break Trump's way. It already is. Trump is getting cross-overs from Dems, indies, blacks, latinos and a chunk of asians.
