Regarding voting machine fraud, Verified Voting has written extensively on the need for each voting machine or ballot to produce a "paper trail", that can be easily and accurately used if a recount is required. https://verifiedvoting.org/
Did you read the Wired article? Excellent analysis on how Republican's unbased fears are running wild and stoking paranoia. Likely in preparation to dispute the election outcome. https://www.wired.com/story/election-fraud-conspiracies-floo...
The only major case of a fraud like thing in the US I know was the 2000 Florida recount when dems had more people vote for the but republican judges throught out enough for them to win. Not subtle in what they did, although it's not usually called fraud because judges did it.
You can often identify large scale fraud by the polls being out of whack with the results.
I’m also not sure why it matters that poll workers are from the same county - that doesn’t make elections secure. People in my county aren’t “neighbors” - I doubt most people would call every random person within 100 miles a “neighbor”. Even if they were, what would that prove?

How can you prove it though? What I see is many steps that require trust in other humans. Not real verifiable elections.
I’m curious what your thoughts are on steps like voter ID to improve election integrity. To me it seems like an obvious and necessary step, and the resistance to it seems suspicious.
