William L. Dayton of New Jersey, who had served with distinction in the Senate, was selected for the Vice-Presidency. His principal competitor in the only ballot which was taken was Abraham Lincoln of Illinois. This was the first time that Mr. Lincoln was conspicuously named outside of his own State. He had been a member of the Thirtieth Congress, 1847-9, but being a modest man he had so little forced himself into notice that when his name was proposed for Vice-President, inquiries as to who he was were heard from all parts of the convention. The principles enunciated by the Democratic and Republican parties on the slavery question formed the only subject for discussion during the canvass in the free States. From the beginning no doubt was expressed that Mr. Buchanan would find the South practically consolidated in his favor. Electoral tickets for Fremont were not presented in the slave States, and Fillmore's support in that section was weakened by his obvious inability to carry any of the free States. The canvass, therefore, rapidly narrowed to a contest between Buchanan and Fremont in the North. The Republican Convention had declared it to be "both the right and imperative duty of Congress to prohibit in the Territories those twin relics of barbarism,-- polygamy and slavery." The Democratic Convention had presented a very elaborate and exhaustive series of resolutions touching the slavery question. They indorsed the repeal of the Missouri Compromise, and recognized the "right of the people of all the territories to form a constitution with or without domestic slavery." The resolution was artfully constructed. Read in one way it gave to the people of the Territories the right to determine the question for themselves. It thus upheld the doctrine of "popular sovereignty" which Mr. Douglas had announced as the very spirit of the Act organizing Kansas and Nebraska. A closer analysis of the Democratic declaration, however, showed that this "popular sovereignty" was not to be exercised until the people of the Territory were sufficiently numerous to form a State constitution and apply for admission to the Union, and that meanwhile in all the Territories the slave- holder had the right to settle and to be protected in the possession of his peculiar species of property. In fine, the Republicans declared in plain terms that slavery should by positive law of the nation be excluded from the Territories. The Democrats flatly opposed the doctrine of Congressional prohibition, but left a margin for doubt as to the true construction of the Constitution, and of the Act repealing the Missouri Compromise, thus enabling their partisans to present one issue in the North, and another in the South.
