In Pennsylvania we have all been amused at the successive detachments of those whom we call guerillas, which have visited Concord to assure you that serious divisions exist among the Democracy of our State. There never was anything more unfounded. The party is now more thoroughly united than it has ever been at any period within my recollection. Whilst the contest continued between General Cass and myself, many honest Democrats, without a particle of personal or political hostility to me, preferred him and espoused his cause simply because he had been the defeated candidate. That feeling is at an end with the cause which gave it birth, and these honest Democrats as heartily despise the ——, the ——, the ——, the ——, the ——, the ——, etc., etc., as do my oldest and best friends. In truth the guerillas are now chiefs without followers. They are at present attempting to galvanize themselves at home through the expected influence of your administration. Their tools, who will nearly all be applicants for office, circulate the most favorable accounts from Concord. They were scarcely heard of previous to the October election, which was the battle of the 23d December; but if we are to believe them, they achieved the victory of the 8th January. These are the men who defeated Judge —— at the election in October, 1851, by exciting Anti-Catholic prejudices against him, and who have always been disorganizers whenever their personal interests came in conflict with the success of the party. Thank Heaven, they are now altogether powerless, and will so remain unless your administration should impart to them renewed vigor. Their principal apprehension was that you might offer me a seat in your cabinet, but for some time past they have confidently boasted that their influence had already prevented this dreaded consummation. Their next assault will be upon my intimate friend, Judge ——, who will, I have no doubt, be strongly presented to you for a cabinet appointment. The Judge is able, honest and inflexibly firm, and did, to say the very least, as much as any individual in the State to secure our glorious triumph. I might speak in similar terms of ——. To defeat such men, they will lay hold of ——, Mr. ——, or any other individual less obnoxious to them, and make a merit of pressing him for a cabinet appointment from Pennsylvania. They calculate largely upon the influence of General Cass, who, strangely enough, is devoted to them, although their advocacy rendered it impossible that he should ever be nominated or elected by the vote of the State.
