After a struggle of some months, the Kansas-Nebraska bill became law. The Missouri compromise was abrogated, and the question of the extension of slavery to the territories was adrift again, never to be got rid of except through the abolition of slavery itself by war. The demands of the South had now come fully abreast with the proposal of Douglas: that slavery should have permission to enter all the Territories, if it could. The opponents of the extension of slavery, at first under the name of "Anti-Nebraska men," then of the Republican party, carried the elections for representatives in Congress in 1854-'55, and narrowly missed carrying the Presidential election of 1856. The percentage of Democratic losses in the congressional districts of the North was sufficient to leave Douglas with hardly any supporters in Congress from his own section. The Democratic party was converted at once into a solid South, with a northern attachment of popular votes which was not sufficient to control very many Congressmen or electoral votes. Immigration into Kansas was organized at once by leading men of the two sections, with the common design of securing a majority of the voters of the territory and applying "popular sovereignty" for or against slavery. The first sudden inroad of Missouri intruders was successful in securing a pro-slavery legislature and laws; but within two years the stream of free-State immigration had become so powerful,in spite of murder, outrage, and open civil war, that it was very evident that Kansas was to be a free-State. Its expiring territorial legislature endeavored to outwit its constituents by applying for admission as a slave State, under the Lecompton constitution; but the Douglas Democrats could not support the attempt, and it was defeated. Kansas, however, remained a territory until 1861. The cruelties of this Kansas episode could not but be reflected in the feelings of the two sections and in Congress. In the former it showed too plainly that the divergence of the two sections, indicated in Calhoun's speech of 1850, had widened to an absolute separation in thought, feeling, and purpose. In the latter the debates assumed a virulence which is illustrated by the speeches on the Sumner assault. The current of events had at least carried the sections far enough apart to give striking distance; and the excuse for action was supplied by the Dred Scott decision in 1857.
