That election was bought and paid for, and for thanks the mob got Bobby and his investigative zeal. They were not amused. Plus, Jack was fooling with somebody’s girlfriend.
And I should have added in my previous post that there WERE plenty of other groups mad at JFK and probably would have killed him given the opportunity. It was just the mob got there first.
I believe old Joe also promised the MOB that his son’s administration would ease-up, not go after them twice as hard.
And there is no disputing the fact that JFK could not have been elected (he didn’t win the popular vote) without Chicago, and the MOB delivered Chicago.
