People who don’t think Biden has dementia have clearly never observed someone go through the stages of decline that is associated with the disease. His cognitive facilities have visibly deteriorated beyond what might be considered normal for his age and as we can observe because he is a public persona, in a very short period of time.
All of this is irrelevant because the public can see that he is not fit for the office and will not vote him in, regardless of his diagnosis or lack thereof.
Yes obviously even a dead guy is better than a fascist but the problem is getting the corpse back in the office.
