You could easily get 1000 Americans to swear that Elvis is alive or they were abducted by aliens or just about anything really. Without corroborating evidence, affidavits are meaningless.
There are something like half a million election workers. They're just regular people. It wouldn't be hard to find 1000 of them who are willing to lie or can't distinguish fantasy from reality.
I'd imagine more than 1000 of them believe the earth is flat and/or was created 10,000 years ago.
If would be more like dismissing UFO evidence from 1000 sworn affidavits from people that work at the Pentagon.
