Answer:
Anti-slavery.
Step-by-step explanation:
Abraham Lincoln did not appear on Florida's presidential ballot in 1860 because he was "Anti-Slavery."
The above statement is true because, as of the year 1860, Florida, a Southern state in the United States is a slave state, and the fact that Abraham Lincoln does not support slavery in his campaign, the state of Florida decided to ensure Abraham Lincoln does not get a vote from them, hence, they remove him from the presidential ballot.
The state of Florida would later join Confederates to fight in the American Civil War.
