You notice that watchers in recent elections get grainy poor photos and video of late night vans, poll workers, poll stations, box stuffers. They look like sasquatch photos from the 70’s.
There are rumors of a postal truck full of ballots, but no hard evidence. Rumors of dumpsters full of ballots but oops they gone now.
If there are shenanigans we have to go Spielberg quality in our evidence gathering.
... yeah rumors. How about sworn affidavit from the driver about his load of ballots, delivered across state lines and parked, then disappeared... Then the Post Office investigated itself, said nothing to see here... Union crooks that trash ballots in Repub precincts. You Need a million watchers and still won’t catch the demonrat cheaters.... ymmv
