Calhoun argued that a war for territory was morally wrong and felt that the Polk administration had been too aggressive in trying to force a war. Anti-slavery Northerners denounced the war as a Southern conspiracy to expand slavery; Calhoun in turn perceived a connivance of Yankees to destroy the South. By 1847 he decided the Union was threatened by a totally corrupt party system. He believed that in their lust for office, patronage and spoils, politicians in the North pandered to the anti-slavery vote, especially during presidential campaigns, and politicians in the slave states sacrificed Southern rights in an effort to placate the Northern wings of their parties. Thus, the essential first step in any successful assertion of Southern rights had to be the jettisoning of all party ties. In 1848–49, Calhoun tried to give substance to his call for Southern unity. He was the driving force behind the drafting and publication of the "Address of the Southern Delegates in Congress, to Their Constituents". It alleged Northern violations of the constitutional rights of the South, then warned Southern voters to expect forced emancipation of slaves in the near future, followed by their complete subjugation by an unholy alliance of unprincipled Northerners and blacks. Whites would flee and the South would "become the permanent abode of disorder, anarchy, poverty, misery, and wretchedness". Only the immediate and unflinching unity of Southern whites could prevent such a disaster. Such unity would either bring the North to its senses or lay the foundation for an independent South. But the spirit of union was still strong in the region and fewer than 40% of the Southern congressmen signed the address, and only one Whig.
