Don't know about Jack. But Arnold Palmer, thankfully, is still alive and relatively healthy for a man of his age. Our local airport bears his name (he put up much of the seed money for it) and he has been extraordinarily generous with our community, hospitals and the like. Even his car dealership is a common site for high school fundraisers such as car washes and the like.
A you might guess from the foregoing, he is a staunch Republican and conservative.
