Breakaway delegates in Baltimore nominate John C. Breckinridge, splitting the Democratic Party
Delegates who had left the National Democratic Convention, together with those who had been refused entry, met at the Maryland Institute in Baltimore. Twenty-one states were represented in this "Seceding Democrats Convention." The gathering nominated John C. Breckinridge of Kentucky as their candidate for president and Joseph Lane of Oregon as vice president. The split in the Democratic Party was now official. (By John Osborne)
