It's all a stalling tactic.
The most important part is done, the hand recount. It's now a simple matter of releasing those results. "We counted X number of ballots with this many for Trump, this many for Biden. That number either matches what election officials certified or it doesn't.
If it doesn't match, within some small margin of error, Maricopa BOS will be unable to defend their position
If the numbers do match, that doesn't mean fraud didn't happen.
There is no way to have secure and anonymous elections.
The closest we can come is in person voting on one day with paper ballots counted right there in the precinct at close of polls. Anything else, which we've been doing for years, invites fraud.
It's this simple. If your a scumbag party or politician running to control million, billions, and trillions of dollars what wouldn't you do to win?
