I’ll say BS. With mail in ballots the centralized counting process, or lack of process, is just too easy to corrupt. Sorry the simplest solution is usually the one. It’s not the voting, it’s the counting.
There are multiple methods.
Fraudulent votes are a major component.
They breached the counting system. Uploaded fabricated results from Dominion server in Serbia. The engineers who did it are whistleblowers. Venezuela, Cuba, China, Iran, Russia, and Serbia, using a server set up by traitor John Brennan
One alone, say ballot box stuffing with mail-in ballots, might be broken up at the last minute.
With several methods, server hacking by foreigners included, they can be sure of the steal.
If one avenue is exposed, they can still cheat by the others.
Of course this is how they do it, by conspiracy or just like Moose Limbs do, in cells that are semi-autonomous and non-communicative with other cells.
