The question is how to know which county you need to do that in. The more you try, the greater the odds of being caught but with margins that small you’d need to attempt multiple states and predict rather accurately how many votes you need to win but not to attract too much scrutiny.

Moreover the problem there isn't the distributed/local control of voting, but the College.

Decentralised could be each counter putting 5000 or so ballots into piles with people wandering around witnessing for various parties all working a rigid process accross the nation. Each count publically announced in the room before witnesses.

Totally standardised, coordinated, and decentralised. But fragmented (structuraly) or incoherent.

But agree would be a million times worse with a single electronic system
