Are you suggesting that claiming to "ace" a dementia test and being able to successfully tell an elephant from a camel might not reassure undecided voters of your mental acuity?
@sir82 ...
Sadly, with a country of 330,000,000 people, we are down to these two choices for our next "leader".
Biden needs time to concentrate on animal figures and Trump asks whether Finland is part of Russia.
Politics aside, in recent memory, if it were Obama, Romney, Bush the Younger, Al Gore, Clinton, Bush the Elder, Reagan, whoever. You may not always agree with their politics but at least there was a measure of intelligence and sanity. (I'm giving Bush the Younger the benefit of the doubt in this comment).
