There is evident in all their utterances of the spring and early summer of 1844, an ardent and almost furious conviction, not only of the necessity but the certainty of success. Mr. Clay was nominated long before the convention met in Baltimore. The convention of the 1st of May only ratified the popular will; no other name was mentioned. Mr. Watkins Leigh had the honor of presenting his name, "a word," he said "that expressed more enthusiasm, that had in it more eloquence, than the names of Chatham, Burke, Patrick Henry, and," he continued, rising to the requirements of the occasion, "to us more than any other and all other names together." Nothing was left to be said, and Clay was nominated without a ballot; Mr. Lumpkin, of Georgia, then nominated Theodore Frelinghuysen for Vice-President, not hesitating to avow, in the warmth and expansion of the hour, that he believed that the baptismal name of the New Jersey gentleman had a mystical appropriateness to the occasion. In the Democratic convention Mr. Van Buren had a majority of delegates pledged to support him; but it had already been resolved in the inner councils of the party that he should be defeated. The Southern leaders had determined upon the immediate and unconditional annexation of Texas, and Mr. Van Buren's views upon this vital question were too moderate and conservative to suit the adventurous spirits who most closely surrounded President Tyler. During the whole of the preceding year a steady and earnest propaganda of annexation had been on foot, starting from the immediate _entourage_ of the President and embracing a large number of Southern Congressmen. A letter had been elicited from General Jackson, declaring with his usual vehemence in favor of the project, and urging it upon the ground that Texas was absolutely necessary to us, as the most easily defensible frontier against Great Britain. Using the favorite argument of the Southerners of his school, he said: "Great Britain has already made treaties with Texas; and we know that far-seeing nation never omits a circumstance in her extensive intercourse with the world which can be turned to account in increasing her military resources. May she not enter into an alliance with Texas? And, reserving, as she doubtless will, the North-western boundary question as the cause of war with us whenever she chooses to declare it--let us suppose that, as an ally with Texas, we are to fight her. Preparatory to such a movement she sends her 20,000 or 30,000 men to Texas; organizes them on the Sabine, where supplies and arms can be concentrated before we have even notice of her intentions; makes a lodgment on the Mississippi; excites the negroes to insurrection; the lower country falls, with it New Orleans; and a servile war rages through the whole South and West."
