Lyndon Johnson actually said...

"I think that every person in this country ought to support the candidate of his choice, and the candidate that he feels will best serve."

"I think you will have to talk to Mrs. Johnson."

"Our people join with yours in mourning a servant of peace, and a friend of us all."

"Anytime, and whenever we think it is appropriate, on any question on which their particular qualifications may suit them."
