In April 1860 Democrats met in Charleston, South Carolina to select a candidate for the upcoming presidential election. The convention was in complete chaos. Northern democrats wanted to nominate Stephen A. Douglas. Southern democrats would not support him because he supported new states having the popular sovereignty right to choose whether they would allow slavery. The convention could not agree on a candidate. Later, in a separate convention, the northern democrats met again and chose Douglas. The southern democrats chose John C. Breckinridge. He was the Vice President of the United States under President James Buchanan.
