mke_bt saidAdd Woodrow Wilson to the list. JFK also had numerous physical maladies. The press has changed so much since Wilson and Roosevelt. Could you imagine the press not reporting that the President uses a wheelchair in this day and age?
True about Wilson, his wife really ran the country during his stroke, which the public didn't fully know. As for Roosevelt and his wheelchair, that was a physical impairment, that conventions of politeness at that time disguised. Yet the public knew about the car Henry Ford gave him, that had all hand controls and didn't require the use of his legs. The US public KNEW it, but it was just bad manners to actually SHOW it.
FDR would be fitted with heavy metal leg braces, and you'll see newsreels of him standing with aides at his elbows, supporting him. But his mind was sharp, and he was a really dynamic personality, who dominated the US political landscape for over a decade, bringing this country through the Great Depression and most of World War II.
But as his heart failed so did his energy and possibly his mind. He was done by 1944 and should not have run for a fourth term (now prohibited by Constitutional Amendment). His weakness may have allowed Stalin to win political concessions for the Soviet Union that a stronger Roosevelt would never have allowed, and that greatly disturbed Churchill.
As for JFK, his back problems were disguised from the public as well. I'm not sure he was ever on meds that would have impaired his judgment, and so therefore I don't have a problem with him maintaining his privacy.
