Arizona officials also indicate they will be releasing an important batch of results tonight, mostly from Maricopa county. Phoenix is in Maricopa. Trump won that county by a slim margin back in 2016 by only 50,000 votes. Voter turnout has already far exceed last elections in that county by a few hundred thousand votes for both candidates, with Biden currently in the lead by 100,000 votes. The AP (and Fox), using their methods, have already marked Arizona for Biden. The remaining votes are mail in so they probably favor Biden and the AP probably has more accurate information to work off of to make that determination.
Statewide, Trump is down by 80,000 votes.
