From much as I could find on the subject, I don't think JFK used Cocaine, at least not regularly. He did use amphetamines, codeine, demerol, methadone, and Ritalin throughout his presidency, though, so cocaine probably would have been too weak for him, anyways. The man was on a doctor prescribed speedball.

I guess in my country the candidate tends to campaign by themselves, maybe their spouse might show up on occasion but they don't say much. The US model where the family get wheeled out to make zingers is strange.

Agree that all of them are nepo babies btw.
