I like to vanity Google search the Dope. Found old FLOTUS/POTUS trivia thread. Left one question unanswered: when was the last time the Presidential couples were united (either both dead or both living)? I initially thought it was 11/21/63, but I realized Herbert was alive but Lou Hoover was dead. So anyone know? In the thread Little Nemo did great legwork finding data, maybe he can help.
