There's only one Kennedy for me - John. You know, the writer and politician. The Navy guy, that guy. You know the one I mean. en.wikipedia.org/wiki/John_P....
(Seriously, Kennedy was about as morally admirable as a politician from Maryland born in 1795 could have been - and would have been an effective President.)
if only Reverdy Johnson had not been from Maryland too, we could plausibly have had a Kennedy-Johnson ticket in the 19th century. no _you_ overthink political trivia from two centuries ago
