The Democratic National Convention for the Election of 1860 was held in Charleston, South Carolina, despite it usually being held in the North. When the convention endorsed the doctrine of popular sovereignty, 50 Southern delegates walked out. The inability to come to a decision on who should be nominated led to a second meeting in Baltimore, Maryland. At Baltimore, 110 Southern delegates, led by the so-called "fire eaters," walked out of the convention when it would not adopt a platform that endorsed the extension of slavery into the new territories. The remaining Democrats nominated Stephen A. Douglas for the presidency. The Southern Democrats held a convention in Richmond, Virginia, and nominated John Breckinridge. Both claimed to be the true voice of the Democratic Party.
