Why do you think that it was possible for Homeless shelters that had 250 beds had 15,000 Mail in Ballots with that address.
Homeless shelters, nursing homes, multi-tenant apartments (no apartment # listed), college dorms and college town housing of all types, hotels, RV parks, empty lots. Wholesale voter fraud.
In 2022 AZ, top 4 democrats on ballot got an extra 250,000 votes from Phoenix and Tuscon that didn't vote for anyone but them. It does take somebody time to fill out 250,000 extra ballots. Even if you don't sign them, which in many cases, they didn't.
