John Kennedy actually said...

"My feeling is that this is a great country, but I think it can be a greater country."

"This is a trying time in the life of our country, but I think in a very real sense if we do our job here, the future can belong to us."

"I really don't see why we should engage in close debate over what you may believe and what I may believe."

"I don't run for the office of the Presidency promising that if you elect me life will be easier."
