I think this post is correct in most respects:

In particular, these two statements are central:

The African Methodist Episcopal (AME) church, has precinct level ballot counting election operations (poll workers) in the key counties [Fulton (GA), Wayne (Mich), Philadelphia and Pittsburgh (PA), Clark (NV), Maricopa (AZ), Dane (WI), etc.] The ballot counting doesn’t need to happen all over the state, just at the key urban county level.

If another 20 million actual American people vote for Donald J Trump the system has an offset. The millions of illegal aliens who have entered the country are generating millions of additional ballots that might be needed.
