Re: Why is this so hard?
If the machine was compromised then of course it would print out a false receipt.
No personal offence but you haven't thought this through or read the research on this subject. You are speculating in an unhelpful way today.
I'm more elderly than middle aged now, and I know your natural reaction to a tech problem is to refine and improve the tech. This is not a tech problem. This is a problem caused by the introduction of tech for no good reason. We don't need to fix election machines, we just need to remove election machines.
Don't fix what wasn't broken.
