No contest for the Presidency, either before or since, has been conducted with such intense energy and such deep feeling. Mr. Clay's followers were not ordinary political supporters. They had the profound personal attachment which is looked for only in hereditary governments, where loyalty becomes a passion, and is blind and unreasoning in its adherence and its devotion. The logical complement of such ardent fidelity is an opposition marked by unscrupulous rancor. This case proved no exception. The love of Mr. Clay's friends was equaled by the hatred of his foes. The zeal of his supporters did not surpass the zeal of his opponents. All the enmities and exasperations which began in the memorable contest for the Presidency when John Quincy Adams was chosen, and had grown into great proportions during the long intervening period, were fought out on the angry field of 1844. Mr. Polk, a moderate and amiable man, did not represent the acrimonious character of the controversy. He stood only as the passive representative of its principles. Behind him was Jackson, aged and infirm in body, but strong in mind, and unbroken in spirit. With him the struggle was not only one of principle, but of pride; not merely of judgment, but of temper; and he communicated to the legions throughout the country, who regarded him with reverence and gratitude, a full measure of his own animosity against Clay. In its progress the struggle absorbed the thought, the action, the passion, of the whole people. When its result was known, the Whigs regarded the defeat of Mr. Clay, not only as a calamity of untold magnitude to the country, but as a personal and profound grief, which touched the heart as deeply as the understanding. It was Jackson's final triumph over Clay. The iron-nerved old hero died in seven months after this crowning gratification of his life. GENERAL JACKSON AND MR. CLAY.
