Please don’t permit the selection of a Democratic presidential nominee who will stumble over and over with senior-moment errors and lapses and misrememberings. And please make sure that the person who wins the nomination is smoothly articulate and whipsmart and never misses a trick. Someone, you know, like Pete Buttigieg. I know it can’t actually be Buttigieg himself because of an army of mule-stubborn African-American voters, but a presidential campaign defined by senior-moment gaffes will be devastating. Make that horrific. It’ll just break my heart.
