"I have political enemies, of course—men who, influenced by party feeling, are not above attacking methods and possibly my official reputation; but personal ones—wretches willing to stab me in my homelife and affections, that I can not believe. My life has been as an open book. I have harmed no man knowingly and, as far as I know, no man has ever cherished a wish to injure me."
