John Kennedy actually said...

"I run for the office of the Presidency in the most difficult time in the life of our country, in many ways the most difficult in a hundred years."

"I am delighted that Governor Collins has accepted this very important task in our national campaign."

"I don't run for the office of the Presidency promising you that if I am elected that life will be easy and the problems all solved"

"I can assure you that if we are successful in January of 1961, that we are going to move ahead in this country"
