I would assume if there are a large number of Biden-only ballots (large enough to show irregularities), the audit part would take care of that. My guess would be calling the name on the ballot and simply asking "Hey, did you do this?". Enough "no's" and there you go - tossed and proven fraud.
Question...who would decide that a Biden only ballot wouldn’t count in a recount?
