"The time has come now for you to choose our successors and to elect a Congress to serve with them."
"This election may decide whether we shall go ahead and expand our prosperity here at home or slide back into a depression."
"My friends, I have the honor to present to you the Democratic candidate for Vice President, John Sparkman of Alabama, and the Democratic candidate for President, Adlai Stevenson of Illinois."
"We have not retreated in the face of this threat."
