California election officials haven’t been able to count all the ballots yet, because under AB 37 they have to accept ballots postmarked by Election Day for seven days after Election Day. So, there’s no way to know exactly how many ballots are outstanding until mail ballots received on Tuesday, November 15 (for this election) are tallied.
Hypothetically, one could contract with “a courier service that is in the regular business of accepting a mail item, package, or parcel” for delivery to any government building (and there are plenty of them) and just have ballots delivered within that seven-day time frame, without any information from that courier service as to when they were “mailed,” and as long as the voter dated the ballot envelope on or before election day, it would be counted.
