"The populist poet of Jacksonian democracy, Walt Whitman, sang the song of manhood and the Anglo-American super race that had been steeled through empire. As an enthusiastic supporter of the US war against Mexico in 1846, Whitman proposed the stationing of sixty thousand US troops in Mexico in order to establish a regime change there "whose efficiency and permanency shall be guaranteed by the United States. This will bring out enterprise, open the way for manufacturers and commerce, into which the immense dead capital of the country [Mexico] will find its way."2 Whitman explicitly grounded this prescription in racism: "The nigger, like the Injun, will be eliminated; it is the law of the races, history.... A superior grade of rats come and then all the minor rats are cleared out." The whole world would benefit from US expansion: "We pant to see our country and its rule far-reaching. What has miserable, inefficient Mexico... to do with the great mission of peopling the New World with a noble race?" In September 1846, when General Zachary Taylor's troops captured Monterrey, Whitman hailed it as "another clinching proof of the indomitable energy of the Anglo-Saxon character" Whitman's sentiments reflected the established US origin myth that had the frontier settlers replacing the Native peoples as historical destiny, adding his own theoretical twist of what would later be called social Darwinism."
