Then to my point - just say, ok, these weren’t segregated, we don’t know how they were handled or where they came from - therefore the election stands as is otherwise it could be tainted in either direction. No recount. Done.
I don't know AZ law, but if the relevant statutes don't make it clear, and AZ did not do a recount, the dem lawyers probably already have a lawsuit ready (they would probably sue even if the law supports not doing a recount). One problem is that Sinema has more money and lawyers than McSally.
I have 100,000 completed ballots in the trunk of my car. Are they going to count them?
