Answer:
They ran two candidates for the presidency
Step-by-step explanation:
During the presidential race of 1860, the major subject of discussion was if slavery should be allowed in the new territories in the West. The Northern and the Southern Democratic Party did not agree in a single candidate or party platform because of this discussion.
The party was divided over the slavery issue, because of that, delegations of 10 southern states left the Democratic Party that was held in Baltimore and held their own for the Constitutional Democrats. This way the Democratic Party had two candidates.
