The 1860 Democratic National Conventions were a series of presidential nominating conventions held to nominate the Democratic Party's candidates for president and vice president in the 1860 election.
The first convention, held from April 23 to May 3 in Charleston, South Carolina, deadlocked after failing to nominate a ticket: two subsequent conventions, both held in Baltimore, Maryland in June, ultimately nominated separate presidential tickets.
Senator Stephen A. Douglas of Illinois entered the Charleston convention as the front-runner for the presidential nomination, and while he won a majority on the first presidential ballot of the convention, convention rules at the time required a two-thirds majority to win the nomination, with Douglas' adherence to the Freeport Doctrine regarding slavery in the territories engendering strong opposition from many Southern delegates: opponents of Douglas's nomination spread their support among five major candidates, including former Treasury Secretary James Guthrie of Kentucky and Senator Robert M. T. Hunter of Virginia.
After 57 ballots over a span of two days, in which Douglas consistently won at least half of the delegates, the Charleston convention adjourned when it became apparent no candidate could secure the required two-thirds of all votes.
The Democratic convention reconvened in Baltimore on June 18, but many Southern delegates were either excluded from the convention or refused to participate. The convention adopted a platform in which it pledged to abide by the decision of the Supreme Court of the United States upon questions of Constitutional Law regarding slavery.[1]
Douglas was ultimately nominated for president on the second ballot (the 59th ballot overall). Senator Benjamin Fitzpatrick of Alabama was nominated for vice president, but he refused the nomination, and was replaced by former Governor Herschel V. Johnson of Georgia.
The Southern Democrats who had boycotted, or walked out of, the Baltimore convention held their own separate convention and adopted a pro-slavery platform, and nominated incumbent Vice President John C. Breckinridge for president, with Senator Joseph Lane of Oregon as vice president.
While Douglas and Breckinridge received a combined 47.62% of the popular vote in the 1860 presidential election, they lost the election to Republican candidate Abraham Lincoln.
