If people are going to cheat at this election, their plan will be same as last election.

Wait till the last hour, see which swing states need only a few votes to push you over the edge, arrive with a small official election team, kick out all the administrators, have very close to exactly the number of ballots you need to push it over, have them come back in and recount, then dip out.

this way, you minimize the impact of your cheating to reduce your chance of getting caught (only the few districts that are close need attention, and only a few piles of pre-printed ballots and small number of people are required).

Their plan will not involve widespread mass media conspiracy lying, because this involves the collaboration of thousands and thousands of people, and among there, there's one democrat who probably thinks "hey, if I leaked this, I'll be a national hero" before the Dems execute them in cold blood a la Seth Rich. They can handle one Seth Rich, but they can't handle hundreds.
