but it wouldn't surprise me in the slightest if his mental decline has gotten worse and is now accelerating even faster. In fact, I would expect that... and that it will continue to decline at an ever accelerating rate.
For Alzheimer's patients the average time between 1st diagnosis and death is 8 years. It wouldn't surprise me if Biden was diagnosed with dementia in 2018 or even before. Of course, we don't know if he has Alzheimer's or not, but it is the most common form of dementia. I believe the only way to know for sure is via autopsy after death. That could well happen before 4 years from now given his health history and age.
Who knows, if he adamantly refuses to step down, jeopardizing the Deep State's plans he might die relatively soon.
