Following the secession of eleven states from the Union after Abraham Lincoln's election to the presidency, Missouri found itself in a quandary. The state had just elected a pro-secessionist governor who actively sought to join the newly-established Confederate States. Governor Claiborne Fox Jackson conspired to capture the St. Louis Arsenal and transfer its arms to the Confederacy; this plan was thwarted when Secretary of War Simon Cameron sent federal forces to back up soldiers at the Arsenal. After a bitter back-and-forth between Jackson and Captain Nathaniel Lyon, Jackson fled south and declared himself governor of a Confederate government-in-exile.

Thanks to this sequence of events, Missouri remained bitterly divided throughout the Civil War, despite remaining officially part of the Union. Anyone who wished to cast a vote in the 1864 election in Missouri was required to take an oath of loyalty to the Union first, a requirement that greatly advantaged the Republican ticket. While Lincoln and Johnson ran on the Union Party ticket, the present ballot is headed "Radical Ticket," likely a pejorative against Lincoln's policies towards slavery.
