Their model was +9 GOP while the current electorate is +11 GOP.
Looks like Sinema could still have the lead, just smaller than +5.
Remember AZ-08 had a +20 GOP (48-27 GOP) mail-in advatage but Debbie Lesko only ended up winning by 4.8.
Have you read the Article. Their Pollster admitted the AZ Senate Race "Leans R" at this Point with new EV Data. Yes, Hillary won Indies but not by almost 20 Points like "Data Orbital" was suggesting in their Poll.
And what you fail to comprehend is that Sinema has this lead even while their polling sample has a GOP advantage of 9%.
