Why did the election of these two men upset norterners?

The election of these two men likely upset Northerners due to their perceived alignment with Southern interests, particularly regarding issues like slavery and states' rights. Northerners, who were increasingly advocating for abolition and a stronger federal stance against slavery, felt threatened by the election of candidates who supported or tolerated the institution. This divergence in values heightened tensions between the North and South, contributing to the growing sectional divide in the pre-Civil War era.
