The democratic split was so severe during the 1860 elections that:

the party disbanded
they ran two candidates for the presidency
they had no candidates running for the presidential election
the majority of the members joined the republican party

They ran two candidates for the presidency

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.
