There needs to be a solid law passed that on election night, every jurisdiction MUST have all ballots submitted by a certain time or they will be negated. This whole weeks upon weeks of “oh, we found ten thousand more ballots” or “hey, here is a ballot box found in storage closet”, nonsense should be squelched lickety split.
It's bad enough when many precincts in dangerous Dem-dominant neighborhoods have no R election judges because no R is willing to drive there and spend the day there. That way, near the end of the polling hours (or after), the four chief and asst chief election judges, who are actually all Dems though 2 of them signed (legally) as R, can vote as many times as needed for people that they know did not show up to vote that day. Unless R's get election judges or poll watchers into every precinct in D areas of the country, major vote fraud will continue. These things happen in small numbers.
Defying the law after the election as new ballots are "found" is fraud on a massive scale.
