Only 96 weeks until first arrest.
I guess there are two alternate strategies that would be…acceptable.
1) Arrest/destroy each candidate as they are offered. Biden is pretty much sunk, so who's next? They must have plenty of ammo ready to fire against each new candidate, leaving them with zero viable candidates to run in November. This, however, shows a problem of accusations of an unfair election and will cause close to 50% of the population to dig in their heels and plug their ears, screaming.
2) Allow a weak candidate to get through and run the election, hoping we have things secure enough to beat them "legitimately". This is a gamble on security that one of their frauds won't succeed in taking the election, forcing us into "plan Z".
Either way, something dramatic will have to happen before the election.
