I understand that one person dropping off 30 ballots is against the law in Pennsylvania. That is what we see on the video.
And if they were duplicate or fraudulent ballots, they cannot be counted.
Again: do you understand how various states control this?
You get a unique bar-coded envelope for your ballot. One.
When you return that ballot in your unique envelope, you can certainly ask for another, but it will not be counted, because your unique envelope was used. If it is damaged, lost or stolen you can get another unique envelope and use either one, but if both are returned, they'll only count one of them.
If PA doesn't use this method, then they truly have idiots running their ballot systems, because that's how it works in other states.
And in CO, they notify you when your envelope is received (so if you didn't send it you can contact them to tell them not to count it) and they notify you when it is accepted (and once counted, they will not accept another envelope from you).
So, it'd seem that whatever videos you're being duped by here have you all freaked out over Nothingburgers. If people at nursing homes are having their ballots dropped off in bulk, then that's an issue PA will need to deal with.
For all we know, this is some MAGA person dropping off empty envelopes for Dinesh's "movie" as a propaganda stunt.
