Things have gotten worse over time, and now America has elected Abraham Lincoln, the nation's first anti-slavery president; he only represents the Northern states; and he will pursue policies that attack the institution of slavery. For twenty-five years this agitation (irritation) has been steadily increasing, until it has now secured to its aid the power of the common Government. A geographical line has been drawn across the Union, and all the States north of that line have united in the election of a man to the high office of President of the United States, whose opinions and purposes are hostile (against) to slavery. He is to be entrusted with the administration of the common Government, because he has declared that that
"Government cannot endure permanently half slave, half free," and that the public mind must rest in the belief that slavery is in the course of ultimate extinction.

Abraham Lincoln's election as president was seen as a direct threat to the institution of slavery by South Carolina and other Southern states. They believed that Lincoln and his administration would work towards abolishing slavery, and this led to their decision to secede from the Union. The Southern states felt that their way of life, which was heavily reliant on slavery, was in danger due to Lincoln's presidency and they believed that leaving the Union was their only option to protect their interests.
