I didn’t predict JFK grandson Jack Schlossberg‘s emergence as a social media star when I put him on the cover of Avenue beside his mother Caroline Kennedy Schlossberg in 2017, but it was already clear he’d be a force to be reckoned with if he chose to be. His well-deserved criticism today of his demagogic relative, lunatic fringe presidential candidate Robert Kennedy Jr.–“his candidacy is an embarrassment”–makes the cover line “Duck, Dynasty,” relevant again, too.
