The two great reasons for Jackson's success throughout his political career were to be found in the strength of the feeling in his favor among the poorer and least educated classes of voters, and in the ardent support given him by the low politicians, who, by playing on his prejudices and passions, moulded him to their wishes, and who organized and perfected in their own and his interests a great political machine, founded on the "spoils system"; and both the Jacksonian rank and file and the Jacksonian politicians soon agreed heartily in their opposition to the Bank. Jackson and Benton opposed it for the same reasons that the bulk of their followers did; that is to say, partly from honest and ignorant prejudice and partly from a well-founded feeling of distrust as to some of its actions. The mass of their fellow party-leaders and henchmen assailed it with the cry that it was exerting its influence to debauch politics, while at the same time they really sought to use it as a power in politics on their own side. Jackson, in his first annual message in 1829, had hinted that he was opposed to the re-charter of the Bank, then a question of the future and not to arise for four or five years. At the same time he had called in question the constitutionality and expediency of the Bank's existence, and had criticised as vicious its currency system. The matter of constitutionality had been already decided by the Supreme Court, the proper tribunal, and was, and had been for years, an accepted fact; it was an absurdity to call it in question. As regards the matter of expediency, certainly the Jacksonians failed signally to put anything better in its place. Yet it was undeniable that there were grave defects in the currency system. The president's message roused but little interest, and what little it did rouse was among the Bank's friends. At once these began to prepare the way for the re-charter by an active and extensive agitation in its favor. The main bank was at Philadelphia, but it had branches everywhere, and naturally each branch bank was a centre of opposition to the president's proposed policy. As the friends of the Bank were greatly interested, and as the matter did not immediately concern those who afterwards became its foes, the former, for the time, had it all their own way, and the drift of public opinion seemed to be strongly in its favor.
