Douglas was the only candidate who won electoral votes in both slave and free states (free New Jersey and slave Missouri). His support was the most widespread geographically; he finished second behind Lincoln in the popular vote with 29.52%, but last in the Electoral College. His 12 electoral votes are the lowest for a Democrat in history. Douglas attained a 28 to 47% share in the states of the Mid-Atlantic, Midwest, and Trans-Mississippi West, but slipped to 19 to 39% in New England. Outside his regional section, Douglas took 15 to 17% of the popular vote total in the slave states of Kentucky, Alabama, and Louisiana, then 10 percent or less in the nine remaining slave states. Douglas, in his "Norfolk Doctrine", reiterated in North Carolina, promised to keep the Union together by coercion if states proceeded to secede: the popular vote for Lincoln and Douglas combined was 69.17% of the turnout.
