I have heard that some people are concerned.
Sorry. Wrong number. Thanks for catching this, @kenobi_65 .
@nelliebly: was that meant to go into another thread (specifically, the one below)?
I will say that the OP has managed to get an impressively wide array of posters, from all stripes, arguing against him. That should be worth some kind of badge.
Go easy on him, maybe he’s had a stroke (no cite).
Cite?
No, I do not.
@Love_Rhombus Well, he’s still president. That’s all I can say. 
Reagan is still president? I thought it was Trump.
That’s Trump. Every time he goes golfing, he has more strokes than he will admit, and lies about it.
Thats what the luciferians want you to think - its actuall Lincoln’s great great great grandson , JFK Jr who is actually president.
The thing that seems to happen to many people who recover from an actual stroke is that the brain reroutes its active signal paths around the damaged tissue. The body, and brain, tends to be quite resilient and adaptable. And, of course, there is that quote attributed to Einstein, that we use a fraction of our mental capacity (sometimes given as 10%, sometime 20%), and while it is not true, there is a lot of redundancy and spare capacity in the animal in general.
In other words, if there were any substance to your concerns, well, there really is not.
Things that are TRULY common knowledge typically do not need a cite. And by “common knowledge,” I mean things that a semi-educated person with a lack of curiosity would probably know. For instance, I have a cousin who simply does not follow the news at all. Yet even she knows who the President is.
Statements like “The USSR shaped 20th-century geopolitics” would not need a cite. Statements like “President Kennedy was prescribed [drug] for his back pain” do need a cite.
That is probably not the best example, as quite a few Americans aren’t very good at knowing who the President is.
Sadly, this was true even before 2021.
I think if you look at the graph, January 20, 2021 is the corner of the hockey stick.
The Venn diagram of those who think the President isn’t the President and those who disbelieve in the hockey stick model is a circle.
