James Buchanan autograph letter signed as Secretary of State, writing to William W. Downing and marked ''Private'' at top. Dated 25 September 1848 from Washington D.C., Buchanan refuses to endorse a Presidential candidate, but predicts a Democratic win. Letter reads in part, ''No person in my position, except Mr. Clay, has ever addressed the people on the subject of a pending Presidential election; & for this, he was severely censured. Whilst custom precludes me from exercising this right, I am not the less anxious for the success of our candidates. Firmly convinced that the prosperity & perpetuity of our glorious union depends upon the ascendancy of Democratic principles, I would take an active part in the canvass, if I were not Secretary of State. Our Candidates Cass, Butler & Longstreet are worthy representations of these great principles & immensely deserve the support of their party. From present appearances, I entertain but little doubt of their election…James Buchanan''. Buchanan would be proven wrong, with Whig candidate Zachary Taylor winning the election. Two pages on bifolium measure 8'' x 10''. Separation along folds including one through signature, and complete split along horizontal fold, else very good.
