> you should be able to comfortably go searching for evidence to falsify it and support the alternative, and fail to find such evidence, confident in your assumption that you won't find it.
The system is confidentially designed to provide little to no evidence of the fraud it allows. Even simple signature and ID checking is banned in California.
The system itself is the evidence of the fraud. It is purposefully designed to hide evidence and prevent detection.
You are obviously an intelligent person but you've allowed your curiosity to be subjugated by propaganda.
The fun part about this is that it depends on facts that nobody actually knows.
If you don't check ID then anyone with a list of registered-but-unlikely voters (or who registers unlikely voters ahead of time without their knowledge) could be voting multiple times and there is nothing to detect it. If you check ID then that doesn't happen as easily, but you still have no way to know if it would have happened in the alternative.
The closest thing to knowing would be if apparent turnout declines in response to checking ID, but a) different elections have different turnout anyway and b) even if you could detect a significant change, one party would then argue that it's a reduction in fraud and the other would argue that checking ID is reducing legitimate turnout, and you still don't know which one it is -- it could even be both.
You are creating an unfalsifiable hypothesis, and not attempting to falsify it.
Why do you believe what you believe? What would be true if it were false? Is that a thinkable alternative? If not, do you really have a hypothesis, or do you have a political belief being presented in the guise of a claim of fact?
