I was never a JFK worshipper myself, being a lifetime Conservative, but even I have to admit that he was greatly revered by his followers. I do think his leadership on the space program is, by itself, enough to assure his place in history. Even though I personally despise everything Kennedy.
I was six years old when Kennedy was inaugurated, and he was a god in my mind. To this day, I still revere him somewhat, but having learned much about him in the intervening years, I don't now consider him to be a great president.
