I agree but I used to live in a rural area that did not have house numbering systems on the county roads. Would Rural Route 2 Box 181 be much different than a PO Box number as a means to creating frauddulent votes?
I would think RR delivery people would notice high volume of ballots going to one address but realized it happens in the big cities, unabated. However, country folk also have more than a modicum of common sense. If a pile of mail goes to one address, chances are the carrier isn’t going to inspect the address on each piece of mail he/she jams in the box, we get a lot of mail to people here who are long-gone. Ow, my head. ;)
