Three presidents died on the 4th of July.
One broke the curse.
It's well known that John Adams and Thomas Jefferson famously died on the same day
– July 4th, 1826. Their simultaneous passing on the 50th anniversary of the signing of the Declaration of Independence is viewed as a wonderfully patriotic cosmic coincidence, or at least a victory of the human will to hang on. (Or possibly some good old-fashioned
euthanasia.)
