The left turned JFK into their George Washington, Abraham Lincoln, Ronald Reagan, Mother Theresa, and Joan of Arc all rolled into one great idealist President who would have made America a dreamy utopia if he had only gotten that second term in office.
It was probably one of the most effective propaganda programs of history and gave his brothers extraordinary power that endured through legislation and Senator power through to 2009 and that has survived to some degree in lessor offices with other Kennedys.
Cuba went communist because of him, World War 3 nearly happened because of him, the Vietnam War happened because of him, the fed bureaucracy became an entrenched monster because of him but hey he signed a tax cut so every republican should worship him.
Pah!
JFK was a mediocre President who made a few good speeches, like the "I am a jelly doughnut" speech in Berlin...thanks to talented speechwriters.
I think the first time anyone referred to the Kennedy Administration as Camelot was after the assassination.
