I have heard he is older than ideal for 4 years....because I have said it myself for 4 years.
But what I have also seen for 4 years....
The right DESPERATELY scraping literally anything up trying to prove that he has "dementia', "cognitive decline", etc.
If you want a specific example shortly after Joe Biden got elected when he drove the new Ford F150 and the right was like OMG 2 STEERING WHEELS!! As if his passenger was sitting there brazenly driving the truck for him while he faked it on his steering wheel. 🙄
If you want more recent examples the "wandering off into the forest" narrative... or "shaking hands with ghosts" bullsh*t.... or anytime he does anything "OMG HE POOPED HIS PANTS"... (which even if that was true would not necessarily mean anything cognitively.)
All this stuff is kind of same thing they tried to do to Hillary in 2016. She was allegedly on her deathbed with whatever alleged illnesses, meanwhile here it is 8 years later she is apparently fine, alive and kickin. I guess she did end up losing that election though so maybe all of that crying wolf worked on some level.
