Does the audit include a verification of the registered voter rolls and mail-in envelopes received?
It should include everything including signature verification on mail in ballots, and special attention to ballots with only the presidential line marked.
I’m sure that more registered Democrats voted for Trump than the other way around. Recounts only recount the same ballots, and unless there’s an erroneous tabulation or total, you’re only recounting the same stuffed ballots again.
