I don’t think they will dare to use dementia for the reason under the 25th amendment. That would confirm Trump’s and the “right wing media’s” claim that he should not be elected because he was suffering from dementia. Maybe they will claim he was incompetent or he will resign instead, (how will Jill take that?).
The MSM and the DS have started the process to vilify him so that the public will agree he should go away. It will be interesting how they spin that after only 7-9 months after taking office he is now unfit to to be CIC and lead the country.
Or the Deep State will kill him one way or another. Better cover story.
All they have to do is pick a day and say that’s the day Biden had a stroke. Something like next Wednesday. Just roll out the plan and let momentum take over.
