The 1860 Democratic National Convention met in April 1860, but adjourned after failing to agree on a candidate. A second convention met in June and nominated Stephen Douglas as the presidential nominee, but several pro-slavery Southern delegations refused to support Douglas, as they demanded a strongly pro-slavery nominee. These Southern Democrats held a separate convention that nominated incumbent Vice President John C. Breckinridge of Kentucky for president. A group of former Whigs and Know Nothings formed the Constitutional Union Party and nominated John Bell for president. Breckinridge and Bell would primarily contest the South, while Lincoln and Douglas would compete for votes in the North. Republicans were confident after these party conventions, with Lincoln predicting that the fractured Democrats stood little chance of winning the election.
