it was an agenda call that is why fnc apparently called it back. It seems they only were totaling absentee votes and not today’s actual voting.
They based it on their super duper reliable polling and the mail in vote so far.
Actually what definitely reminds are the votes from early voting which arrived today and yesterday and probably even before, lot of others.
in 2016 AZ was declared for Trump only Friday after election, we count votes very slowly!
