President Biden’s refusal to undergo a cognitive assessment is wrong on the medical merits and wrong as a matter of political calculation – unless, of course, he fears testing would reveal problems that would further imperil his candidacy.

Biden’s explanation for refusing testing is unconvincing. It is, frankly, an insult to voters who saw what they saw at the debate and in other settings, and who reasonably want assurances that the president is capable of serving another four years.
