Statement Following Victory in the Presidential Election
I am deeply sensible of the honor done me by the American people in thus expressing their confidence in what I have done and have tried to do. I appreciate in the full the solemn responsibility this confidence imposes upon me, and I shall do all that in my power lies not to forfeit it. On the Fourth of March next I shall have served three and one-half years, and this three and one-half years constitutes my first term. The wise custom which limits the President to two terms regards the substance and not the form. Under no circumstances will I be a candidate for or accept another nomination.
