Someone on GAW introduced me to the "Ford Play" yesterday. Nixon's VP was originally Spiro Agnew. Agnew resigned in 1973 over an income tax scandal and was replaced by Gerald Ford. Less than a year later, Nixon resigned and Ford became POTUS without ever receiving a vote. This is something to keep in mind.
edit: There is potentially a Constitutional loophole that could even allow for Obama himself to become POTUS for a third term. The 22nd amendment prohibits anyone from being "ELECTED" to POTUS more than twice, but as you can see from the Ford Play above, Ford was never elected to POTUS at all. Something else to keep in mind.
edit 2: since I got stickied (Thanks), I want to add that I'm not making a prediction here at all. Even if research on this idea checks out, I would still say that it's only one of many possible DS plans. Not all plans get used. Not all plans work out. Just something to keep in mind.
Well, when the text was written, I'm sure (or am I?) that the concern was innocuous and a reasonable attempt to deal with potentially difficult extenuating circumstances... perhaps the powers that be never envisioned losing control to the point that the law and mechanics of the legal processes might be utilized by others against them? Humans are ridiculous and do ridiculous things, often...
Sorry if I've been unclear. This isn't talking about a case of resignation, but declaration of temporary "incapacity" to perform the duties of president. Trump resumes his power and duties once that incapacity is lifted. So if hypothetically, he informed the Speaker & PPT that he was incapacitated, chalk it up to "Covid issues" on Nov 12, he could simply resume his office on Dec 3rd or earlier, by informing the Spearker & PPT that he's a ok. If it's self-imposed, it's self-reversed if that makes sense. VP Pence would be acting POTUS during that span. Interesting date if I recall, VP Pence's Space Force remarks were on Dec 20th? Pelosi could have been licking her chops thinking "Oh Trump is going to die from the rona and then we can impeach Pence!" Still a conspirator, but part of the move to get rid of Trump and Pence and all opposition to their scheme. She's so stupid to consider that it'd all be part of the Patriots' plan.
Going off this revised timeline, then Pence resumes VP role on Dec 21 and the "count" on Jan 6 is procedurally valid, or at least appear as such. But if the military was already in control and the "inauguration" was a charade anyway... just theorizing the possibilities
