I've recently had US mail take 11 days to arrive that normally takes one day to arrive. The mail system has had a lot of problems lately. When a person sends in mail, it's somewhat out of their control now as to when it arrives. Your position that they just shouldn't be counted is unreasonable on it's face. I'm going to take a wild guess here and say you're voting Republican, since that's the party that seems to be focused on suppressing votes.
