Love that piece. It&#x27;s worth pointing out also that Keith was there only for the final year of office, rather than near the beginning, which is one of the best pieces of anecdata against the post-1994 ongoing dementia theory (which a priori I still think is more likely than the &quot;playing dumb&quot; theory). There is of course other anecdata on Bush not being as intelligent as Keith claims, but the big issue that should make most people have low confidence in either extreme is it&#x27;s hard for people to form an accurate mental model of the President.
