"I hope it is a chance, as it has been in our history, for the United States to make a determination as to what it wants to be and what it must do."

"In my judgment, it wants to be not only a great country, which it is; it wants to be a greater country."

"This issue separates Mr. Nixon and myself and it separates the Republican and Democratic Parties."

"I believe that we stand for rebuilding the United States, for developing our economy, for moving ahead here at home, and building our strength around the world."
