Correct.
The democrats seceded from the Union rather than run a split government with the newly elected Republicans.
The Republicans had the Presidency for the first time, and the House by a slim majority.
The democrats held the Senate and controlled the Judiciary.
The democrats would not tolerate even an ounce of compromise - they chose to initiate a bloody civil war.
The democrats and republican of 1860 are very different from those of today.
