Republicans need to flood these with fake ballots. The demon rats will never stop cheating until cheating does not work.
Fake ballots in the drop boxes will be irrelevant. The drop boxes just make it easier to substitute. By 2022 the Democrats will have a whole set of preprinted ballots to simply swap for the contents of each drop box. they do not have to separate them into Dem and Rep votes, just swap for the whole lot.
