AZ is provable af. That's why I don't think it's just about proving it - that'd be too easy. They wouldn't need to go through each and every ballot under a blacklight if they could just find all the missing ballots. Those alone, I reckon, could have tipped the tide with a simple recount if that were the case.

The D's must have realized they were going the full 9 yards with this thing, which means they were doing everything they could to cover their tracks. They must have been in such a haste that they didn't realize the huge brush sweeps they were making were simply making it easier to track not necessarily the who but the what. If this is coordinated, which given how widespread it is in AZ there leaves little doubt, then all they need to do is follow the crumbs to know exactly what they should be looking for, which in turn would catalyze every other audit where fraud is more subtle.
