The Republican Party held its second national convention on May 16, 1860, in Chicago, Illinois. It adopted a moderate stance on slavery and was against its expansion, although some delegates wanted the institution abolished altogether.
The two frontrunners for the Republican presidential nomination were Lincoln and New York Senator William Seward. After three votes, Lincoln was nominated with Hannibal Hamlin as his running mate.
Democrats Split Over Slavery
The Democratic Party was in shambles in 1860. They should have been the party of unity, but instead were divided on the issue of slavery. Southern Democrats thought slavery should be expanded but Northern Democrats opposed the idea.
States’ rights were also hotly debated. Southern Democrats felt states had the right to govern themselves while Northern Democrats supported the Union and a national government.
With such confusion among the ranks, it was unclear how the Democratic Party would ever nominate a candidate for the 1860 election. But on April 23, 1860, they met in Charleston, South Carolina to decide their platform and identify a nominee.
Stephen Douglas was the frontrunner, but Southern Democrats refused to support him because he wouldn’t adopt a pro-slavery platform. Many walked out in protest, leaving the remaining delates without the majority needed to nominate Douglas; the convention ended without a nominee.
The Democrats met again two months later in Baltimore. Once again, many Southern delegates left in disgust, but enough remained to nominate Douglas as their presidential nominee and his running mate, former Georgia governor Herschel Johnson.
Southern Democrats nominated John Breckinridge, a supporter of slavery and states’ rights, to represent them in the election. Oregon senator Joseph Lane was his running mate.
Constitutional Union Party
The Constitutional Union Party was mainly made up of disgruntled Democrats, Unionists and former Whigs. On May 9, 1860, they held their first convention and nominated Tennessee slaveholder John Bell as their presidential nominee and former Harvard University President Edward Everett as his running mate.
The Constitutional Union party claimed to be the party of law. They took no official position on slavery or states’ rights, but promised to defend the Constitution and the Union.
Still, Bell wanted to offer a compromise on the topic of slavery by extending the Missouri Compromise line across the United States and make slavery legal in new states to the south of the line and illegal in new states north of the line. They hoped to sway voters who were upset with the divisiveness of the Democratic Party.
