So far the tally is Mitchell 71,077 and JD 65,122 or a difference of about 6,000. It depends on how many absentee ballots are for Maricopa Ccounty. Sounds like a lot to make up, but nothing is impossible.
When I was helping at Kyl's campaign office he stopped by and spoke to the group. According to him about 50% of Republicans had requested absentee ballots and that's who we were calling from the phonebanks that day since very few had as yet been returned.
