the Missouri Compromise, which the South had welcomed. However, the Supreme Court’s ensuing 1857 'Dred Scott' decision declared that the Constitution protected slavery in all Territories. Douglas was challenged for his Senate seat by Abraham Lincoln in 1858, and narrowly won re-election, after the Lincoln-Douglas debates, by professing the Freeport Doctrine, a de facto rejection of Dred Scott, with militant Southern "Fire-Eaters", such as William Yancey of Alabama, opposing him as a traitor. Many of them openly predicted a split in the party and the election of Republican front-runner William H. Seward. The 1860 Democratic National Convention convened at South Carolina Institute Hall (destroyed in the Great Fire of 1861) in Charleston, South Carolina, on April 23, 1860. Since Charleston was the most pro-slavery city in the U.S. at the time, the galleries at the convention were packed with pro-slavery spectators. Party Platform Disagreement Urged by Yancey, the delegations from seven Deep South states (Alabama, Arkansas, Florida, Georgia, Louisiana, Mississippi, and Texas) met in a separate caucus before the convention. They reached a tentative consensus to "stop Douglas" by imposing a pro-slavery party platform which he could not run on if nominated. The "Fire-eater" majority on the convention's platform committee, chaired by William Waightstill Avery of North Carolina, produced an explicitly pro-slavery document, endorsing Dred Scott and Congressional legislation protecting slavery in the territories. Northern Democrats refused to acquiesce, as Dred Scott was extremely unpopular in the North, and the Northerners said they could not carry a single state with that platform. That would end Democratic hopes of retaining the White House, as no previous candidate had won the presidency without winning either New York or Pennsylvania, and only four (John Adams in 1796, James Madison in 1812, John Quincy Adams in 1824, and James Buchanan in 1856) had been elected without winning both. Douglas and supporters thus preferred the 1856 Cincinnati platform, pure and simple, without explanation or addition. On April 30th, the minority (Northern) report was substituted for that of the majority (Southern) report by a vote of 165 to 138. The question next in order before the Convention was upon the adoption of the second resolution of the minority of the committee. On this question Alabama, Arkansas, one of Delaware's delegates, Florida, Georgia, Louisiana, Mississippi, and Texas refused to vote. The Douglas party abandoned the vague second resolution and it was defeated by an overwhelming vote of
