Lyndon Johnson actually said...

"This Nation deserves and must have a capital city which is in the very front rank in respect for law by its citizens, and in safety for its residents and visitors"

"The first prospect is the conquest of outer space."

"As long as I am in a position to do so, I will try to contribute what I can to what all of you have envisioned as a most worthwhile and public project."

"We are convinced that recessions are not inevitable, and sustained prosperity is our realistic objective."
