Basically it comes down to the fact that you can't verify our elections. Everything they fight for is another way to remove ways to verify. The big one now is mail in. Once the ballot comes in the outer envelope is confirmed by signature. Once this step is done the ballot and that envelope are separated, it can never be checked again. If ballots are added to the pile at that point they are assumed good. Since signature verification was turned off (numbers were not normal) someone could have sent in tens of thousands of ballots to be matched with people who had not yet voted. Next is fixing and adjudication, if there is an error then a poll worker can change what is on the ballot. Poll workers had writing tools. If scanner didn't work (tunable parameter) then scan was shown to worker who could pick what they wanted. At the end of the day the vote totals need to be proven to the people, not the other way around. If you can't do this then it is by design and the election is invalid.
